When Dr Nick Beard met up with Richmond he had just finished working for Coopers and Lybrand and was on a course at Imperial College while also doing some free-lance journalism buy cheap tadalis sx 20mg on-line erectile dysfunction meds online. James Le Fanu cheap tadalis sx 20mg mastercard erectile dysfunction treatment without medication, who joined later cheap 20 mg tadalis sx free shipping erectile dysfunction icd, though working as a doctor was also a free-lance journalist. In various articles, Duncan Campbell was to make much of the idea that those he attacked were at the centre of private medicine, and yet those he was working with were often supported by private interests. As the campaign began to gather members, others with a Wellcome connection joined. Dr Jeremy Powell-Tuck, for example, had been a Wellcome Fellow and Sir John Vane, who joined with his wife Daphne Vane, had recently been one of the most senior scientists at the Wellcome Laboratories. A number of those who were to join the Campaign soon after its launch were associated with the processed food industry. John Garrow and Arnold Bender, whose wife became the membership secretary in May 1990, had both previously been grant-aided by 7 large processed food concerns. One in particular, Professor Tim McElwain, must have seemed like a prestigious catch. By the first months of 1990, the Campaign literature was quoting the names of those who although they had been associated with the campaign from the beginning had never been listed as members before: Dr David Pearson, the allergy specialist from Manchester, Duncan Campbell who had been involved from the beginning with Nick Beard, and a medical sociologist with a good reputation in the field of orthodox medicine, Dr Petr Skrabanek of Dublin University. The Game Within a couple of months of its launch, the Campaign Against Health Fraud had produced a 8 newsletter. It was not as professional as its American counterpart but it provided a good platform for the Campaign to promote attacks and debunking projects which it had initiated. Caroline Richmond seemed most concerned that journalists got the proper view of health matters. The strong American flavour of the Campaign showed clearly in their choice of books they reviewed. In June 1989, Michael Baum gave an interview to the Journal of Complementary and Alternative Medicine. Alternative and complementary therapists would be welcome to join the campaign as long as they agreed with its aims. The few natural medical practitioners who tried to join were usually turned down, without any reason being given. As in the main they knew nothing about alternative and complementary medicine, and some like Caroline Richmond had no clinical experience, it is difficult to see from where they thought their authority in this judgemental capacity came. The vitamins to increase intelligence alluded to the work of Larkhall Natural Health and Cantassium products. Hair analysis related to the work of Biolab and Stephen Davies and diets which promise to counteract childhood hyperactivity alluded to the work of Belinda Barnes on child hyperactivity. In fact, in each of these cases there were mountains of referenced work and scientific papers, none of which were ever alluded to by the Campaign. By the time the first newsletter was published, it was evident how the Campaign were to go about prosecuting their complaints against non-pharmaceutical treatments. The Campaign even made overtures to the Department of Health, asking if they might be formally recognised as a prosecutorial agency by them. In the discussion which followed, Professor Vincent Marks, Professor John Garrow, Wally Bounds, Dr Iain Chalmers and Dr Jeremy Powell-Tuck all agreed that money could be taken from any source. The Campaign felt that it had been penalised when earlier in the year it had been refused charitable status because of its campaigning activities. The meeting decided to change the name of the organisation from the Campaign Against Health Fraud to HealthWatch. The point of this cosmetic exercise was to make the organisation appear less combative and more charitable. It also placed HealthWatch in the context of a number of other groups, mainly set up by the police: Neighbourhood Watch, Homewatch, Carwatch. In the following year, 1991, though its campaigning zeal had not abated and it had done immense damage to a range of alternative and natural practitioners, it was granted charitable status. The British Health Fraud Philosophy The modern health fraud philosophy is extensive and complex, but not really a philosophy, more a series of post hoc defensive arguments for orthodox medicine. At the heart of these assumptions is a simple equation: anything which challenges the monopoly hold of the chemical companies on food production and pharmaceuticals, the professional status of doctors, or the ruling paradigms of industrial technology should be attacked. Much is made by activists of the fact that the health-fraud philosophy is based upon science. Quite the opposite, they are usually highly personalised and apparently given weight by unsupported assertions. This article purports to be a look at the fortunes of complementary medicine as we approach new European regulations in 1992. The article begins with a brief introduction which lampoons complementary medicine (the article is accompanied by one large and one small photograph of individuals undergoing acupuncture treatment; both pictures are visual jokes). The latter has recently pointed out the dangers of creating fashionable herbal remedies from garden plants. For example, camomile which is often taken as tea is now thought to cause 16 vomiting if taken in large doses. But they masquerade as "nutritional supplements" in order to evade the strict rules on efficacy, safety and product promotion which the Medicines 18 Act imposes on conventional drugs. Far from being natural and safe, remedies sold in health food shops, can have disturbing toxic effects. Excessive intake of both fat and water-soluble vitamins can result in severe toxic effects. Vitamin B6 causes peripheral neuritis (inflammation of the nerve ending) at daily doses above 200mgs: and vitamin C is known to increase the bioavailability of oestrogen, so 19 converting a low-dose contraceptive pill into a high-dose one. On January 7th 1991, Derek Jameson interviewed Professor John Garrow, at that time 20 Chairman of HealthWatch, on Radio 2. Professor Garrow put forward the HealthWatch line, saying firstly that vitamin supplements were of no medicinal use and secondly that some of them were positively damaging. Lots of these things which are sold in health food shops — so-called health food shops — as if they were foods, really are being sold as 21 medicines to make people healthier. Professor Garrow, like Professor Bender, has a consuming passion against health food and health food shops. None of the substances added to processed foods go through trials, or are tested over time for adverse effects. Vitamin producers must be the only groups within the capitalist economy, (apart from criminals such as drug dealers) constantly criticised for making profits. For example, vitamin D keeps you young and beautiful, vitamin E boosts your sex drive and potency, vitamin A is meant to stop you getting cancer, vitamin B6 retards ageing and prevents tooth decay, and vitamin C, as we all know, stops you catching a 25 cold. Viv Taylor-Gee moved the item to its logical conclusion, before interviewing the expert, Professor Vincent Marks. Once again we are given a truncated, anecdotal case history which tells us next to nothing about the clinical condition of the woman involved. After all most people know that while an aspirin can stop a headache, it would not be advisable to take a whole bottle to combat a bad headache. If you take large quantities of halibut liver oil capsules to make yourself beautiful you will end up with kidney failure. The programme did not make it clear that Vincent Marks was an active member of HealthWatch, or that he has spent most of his professional life persuading people that sugar does you no harm — even in megadoses.

Bewley Use of the Mental Health Act could also be seen as a threat to pregnant women generic tadalis sx 20 mg on-line erectile dysfunction or cheating, except that it is correctly applied only to enforce non-consensual treatments for psychiatric illnesses purchase 20mg tadalis sx mastercard erectile dysfunction medicine name in india. If a woman is mentally incompetent through such an illness buy tadalis sx online now erectile dysfunction medication uk, decisions about interventions can be made (such as consent for Caesarean section) in her ‘best interests’, but abuse of this provision is not to be encouraged. If a woman had Lassa fever (often fatal and highly infectious through airborne passage) it would be justiWed to quarantine her (and override her right of liberty) as she is presenting a serious danger to others and cannot voluntarily stop breathing. A man with Hepatitis B (often fatal though not highly infectious, and transmitted only through close con- tact with bodily Xuids) presents a danger to others only if he engages in certain activities (such as sex or blood donation). Quarantine might be used as a last resort only if many people with Hepatitis B neglected their obligations to others, and would wrong those who would not have put others at risk. If society could increase the likelihood of a drug-taker stopping with oVers or non-coercive threats, but does not, then if she continues to take drugs she is less reprehensible than if she had rejected such oVers or threats, although she is not guiltless. Unlike the alcoholic driver, the pregnant alcoholic cannot separate taking alcohol from the eVect on the fetus – although she could avoid other additional reckless behaviour, such as driving when intoxicated, she cannot avoid giving the fetus a dose of the drug as she satisWes her craving. The two behaviours, satisfying the craving and delivering alcohol to the fetus, cannot be separated, even if she would like to do one but not the other. It is diYcult to know what to make of this conclusion except to note that it must be impossible to determine which pregnancies are conceived recklessly, and what would be an appropriate punishment. If one woman cannot respond to the threat, and another can but did not, both will have positive urine tests but only one persists in intentional wrongdoing. If punishment should be reserved for wrong acts performed freely, then it would be wrong to punish merely for failure to respond to a threat (as this includes both women who can and cannot stop their harmful behaviour). Punishment should be limited to those cases in which harm has been caused by the behaviour which was freely performed, and where there was intent to cause harm. Punishment does not undo harm nor prevent it, as it can only be used after a wrongdoing, and therefore must be the least preferred option in terms of changing behaviour. However, the existence of punish- ment after birth might act as a deterrent against harmful behaviours earlier in pregnancy, and thus it joins the array of threats available to society to inXuence behaviour. Bewley Moral ranking of different strategies The order of preference of strategies to inXuence behaviour is: (1) oVers (or incentives) over threats; (2) non-coercive means over coercive means; with (3) physical force and punishment being the least preferable. They need not be mutually exclusive (though some are, such as the promise of medical conWdentiality and the revealing of urine sample results to the police). It is permissible to use oVers and non-coercive threats when women can stop harmful behaviour (although threats need extra justiWcation over oVer), whereas coercion is only permissible, if at all, when women cannot stop freely. The will of a drug-taker Frankfurt’s account of freedom reXects well the complexity of autonomy, and presents a way to unravel the drug addict’s intent. He describes what distin- guishes us as human beings as our ‘ability to form second-order desires’ (Frankfurt, 1971) – only human beings can want to want something. Al- though a woman might have conXicting Wrst-order wants, it is the identiWca- tion with a second-order desire that determines the kind of person she is. Her Wrst-order desire to take drugs over- whelms another Wrst-order desire to do the best for her fetus, and possibly a second-order desire to be a drug-free woman. Real life may be more complicated, as the Wrst- and second-order desires of an addict might change throughout the day, as the cravings wax and wane, or through- out the pregnancy, as the fetus grows and interacts. M1 may stop taking drugs either because she is mindful of her duty and does not wish to harm her baby, or because she is reluctantly goaded into stopping. When a mother wishes to do the best for her baby, the result Restricting the freedom of pregnant women 141 of this oVer corresponds to one part of her will and her interests. The existence of a future punishment is in itself a present threat, but if it is in society’s armamentar- ium, it acts as a threat to all pregnant women. A drug addict who reacts to falling levels or shortage of supply with feelings of severe discomfort (withdrawal syndrome) has no choice but to respond with the reasonable and purposive action of buying or Wnding more drugs. The only way to stop her taking drugs is by force, for example, by incarceration to (hopefully) cut oV her supply of drugs, an external coercion corresponding to the inner compulsion to take drugs. Some soft cheeses contain the listeriosis bacterium, which can cause miscarriage, fatal intra-uterine infections and premature labour (with all its consequent com- plications). If eating soft blue cheese and taking heroin had the same adverse eVects on fetuses, but an addict’s discomfort on stopping heroin was marked- ly worse, then the mother who continues to eat gorgonzola would be more culpable than the woman who continues to take heroin. To avoid suVering severe discomfort, by withdrawal of the drug M2 craves and is compelled to take, the rational and reasonable action is to avoid giving a sample of urine, or miss the clinic. Antenatal care, even in the presence of drug-taking, is of beneWt for picking up other diseases of pregnancy, such as diabetes, pre-eclampsia and growth retardation, and it 142 S. Indeed, the policy of British antenatal care and drug maintenance programmes is to stabilize registered addicts on drugs prescribed by licensed doctors. If the woman attends the antenatal clinic at the same time, two potential improvements to her baby’s health are made even before drug reduction (De Swiet, 1989). The complexity of judging and influencing maternal behaviour With this complex model in mind, the drug-taking pregnancy can be viewed not merely as a grave danger to the fetus due to maternal failing, but as an opportunity to oVer intervention and improve fetal health. The pregnant drug addict may be harmed, or even die, as a consequence of her drug-taking, and thus the incentive to improve her own health may be added to fetal incentives. If her will is in conXict, as described earlier, she has the opportunity to identify more strongly with that part that wishes to do the best for her fetus, or wishes not to be a drug addict, and thus become more truly an autonomous person. If, without drug treatment programmes for pregnant women (Chavkin, 1990), she misses this opportunity, society fails both to aid her fetus and to help her realize her autonomy and potential. Strategies that threaten her, or that through fear or interaction with her compulsion diminish rational and reXective self-evaluation, reduce her autonomy (already reduced by addiction). Other incentives that might encourage M2 to minimize harm to her fetus, such as public education, free and conWdential health care, non-judgemental attitudes and access to social service help, will get drug-takers into clinics. Widening the scope Several more qualiWcations still have to be considered before limiting preg- nant women’s freedom: (1) there should be a real and serious risk to a particular fetus; (2) as a woman’s freedom is increasingly interfered with, so the justiWcation for the limitation should become stronger; (3) there has to be no less drastic method for achieving the same end; (4) the harm prevented should not be less than any harm caused; and (5) if freedom is limited, women are harmed by interference with their basic right of liberty (albeit justiWably, and thus not wronged) and there is a case for compensation. If the risk is very remote – for example, every millionth pregnant woman walking on icy pavements falls over and suVers a stillbirth – that would not seem to justify keeping pregnant women indoors all winter. If the risk is of trivial harm – let us say that listening to commercial radio made babies respond by smiling to advertising jingles – that would not justify banning pregnant women from listening to the radio. Increasing restrictions on liberty, increasing justification An example of justiWable limitation on freedom might be long-distance air travel close to delivery. It seems reasonable to balance the small risk of premature delivery and a great limitation on freedom if women could not travel at all against a higher chance at term and less limitation on freedom. Bewley (embryo-deforming) poison gas dioxin blowing towards a city, a justiWcation of forcibly rounding up the pregnant women to transport them away could be based on avoiding harm to their fetuses. If preventing fetal harm overrides women’s rights to freedom, or bodily integrity, it can also be used to override their wishes regarding the continuing of the pregnancy. The arguments can boomerang back to argue for enforced abortions (if abortion is justiWed as the killing of a being without full moral status), when an abortion is a lesser wrong than allowing the continuance of a pregnancy that will lead to a life of suVering. Only the most draconian measures (such as screening the entire female population for pregnancy) would be able to identify those women whose behaviour in early pregnancy is an avoidable source of harm. If a woman cannot work in certain jobs there should be no penalty, such as dismissal, as this would act as a strong disincentive to tell the truth, or even as a pressure towards termination. There are good reasons to doubt the eYcacy of threats when a mother is addicted to drugs, and it is wrong to punish her for behaviour that is compulsive. One comprehensive strategy might be to have a ‘hands-oV,oVers only’ system which should not deter those women who cannot stop drug-taking from seeking health care, but does not tackle indiVerent women who only stop under threat. Collins and others, ex parte S, 1998)and have not been prosecuted for drug-taking in pregnancy or the resulting harms, although children can be taken into care after birth.
They are calibrated for a number of individual radionuclides so that the activity can be measured directly generic 20 mg tadalis sx otc impotence forums. Alternative models designed for the measurement of beta emitting radionuclides are also available but are less likely to be required buy tadalis sx 20mg fast delivery erectile dysfunction jokes. The instrument chosen will be influenced by the range 20 mg tadalis sx with amex impotence remedy, geometry and activities of the nuclides handled. Recent publications that deal with design, calibration and use of calibrators should be consulted for further information. Consistency testing is useful, particularly when calibration is not easily performed, or can be done only occasionally. The department will need a long lived comparison source such as 137Cs (half-life 30 years). However, the half-life of Co of 271 days means the source will need to be replaced every few years. High voltage checks are necessary to ensure the supply to the ionization chamber is adequate. Background measurements and adjustment to zero ensure that any unnoticed radioactive contamination of the calibrator can be detected so that artefacts can be eliminated from measurements. The accuracy of the instrument should be tested with a reference source of activity whose activity has been certified by an appropriate authority. This same source can be used to test the precision of the instrument by performing at least ten repeated measurements of its activity. The constancy of response can be determined using the comparison source to ensure that the calibration factors used are appropriate and do not vary. The value of a reading on the individual settings should decline according to the half-life of the radionuclide in the comparison source. The linearity of the instrument should be checked by measuring a source 99m of Tc whose initial activity is as high as possible, over a period of several half-lives, in order to check that the response of the instrument is linear over the range of giga- to kilobecquerels. Minimum recommended monitoring equipment From all the monitoring devices described, the minimum requirements for a nuclear medicine department are given below. Radionuclide calibrator A simple device is required with a digital readout and preset settings for common radionuclides. Scintillation counter A simple counter with a single sample well for in vitro tests is required. Scintillation counter A gamma spectroscopy system with a well or cylindrical scintillation detector is required. Zone (area) monitor An ionization chamber, Geiger counter or scintillation counter at a fixed position is required, with either a visual or an audible alarm (or both) at variable preset values. Probes for external organs In vivo counting probe systems are used for measurement of thyroid uptake and kidney function, as well as for other more specialized counting. Whatever the application, however, counting systems have a common specifi- cation: (a) A large volume NaI scintillation detector, typically 5 cm diameter by 5 cm thick, to allow both good sensitivity and high detection efficiency for a range of radionuclide photon energies. The collimator is made of lead or another high density material; it is designed to allow a reasonably sized sensitive area, whilst minimizing inter- ference from other sources of radiation in the body. For measurement of kidney function, the ideal counting system has three probes: one for each kidney plus one to measure the blood and tissue background. When purchasing a probe system, one must ensure that a set of low activity spectrum calibration sources is provided. These are crucial, as they are used to set the single channel spectrum analyser to the required counting energy. The sources should have a relatively long half-life, a distinct photon energy (or energies), and cover the required energy range, usually 60–511 keV. Surgical gamma probes The use of surgical probes for localization of activity which can be traced and surgically excised has been of interest since 1949. In this section emphasis is placed on the use of probes employed for detection of 99mTc radiopharmaceuticals. The technique of sentinel node localization needs multidisciplinary co- operation between nuclear medicine physicians, surgeons and pathologists. Success in detecting the sentinel node depends on many factors related to the sensitivity of the detector, the spatial and energy resolution and geometric efficiency of the detector, the radiopharmaceutical injected, the rate of clearance from the site of injection and the uptake in the sentinel node. Detectors are made by various manufacturers, and the preference between different types requires knowledge of the basic physics principles, which are summarized below. Is it for the purpose of sentinel node localization only for early breast cancers and malignant melanomas or for the intraoperative detection of residual or recurrent tumours such as colorectal cancer, thyroid cancer or parathyroid adenoma? The user must familiarize him/herself with different probes and have experience in operating them. A surgical gamma probe is based on either a scintillation detector or a semiconductor detector. Scintillation detectors consist of either NaI or CsI, either 14 or 19 mm in diameter, with a photomultiplier tube and amplifier. The signal intensity of scintillation detectors is higher than that of semiconductor detectors, but their energy discrimination is inferior. Semiconductor detectors consist of either cadmium telluride or, more recently, cadmium zinc telluride. They are significantly more compact than scintillation detectors and therefore more suitable for intraoperative use. When purchasing a probe system for use in surgery, the following factors should be taken into consideration: (a) Shielding (collimation) from scattering is important for improved local- ization and improved spatial resolution. Shielding may be either integral in the design of the probe or in the form of removable collars of a heavy attenuating material. It is advisable to use collimators when there is adjacent activity next to the sentinel node. Well counters Well counters are used for low activity, high efficiency counting of in vitro samples, and are available either as manually operated single sample (or limited number of samples) devices or as fully automatic, multiple sample counters. All well counters use large volume NaI detectors in the form of a well, where the sample is virtually surrounded by the detector. Ideally, they should have the following capabilities: —Automatic photon spectrum calibration, with continuous correction for drift; —Ability to select and count multiple radionuclides; —Automatic radioactive decay correction for the selected radionuclide(s); —Variable counting time; —Sample identification; —A printed report for each sample including sample identification, counting time, energy selected and counts; —An indication of errors in the electronics or mechanical sample changer. Purchasing a nuclear medicine computer Computers have been central to the practice of nuclear medicine for many years, particularly as the extraction of functional information commonly necessitates image analysis. Computers form an integral part of imaging equipment, providing on-line acquisition and data correction to improve instrument performance, essential functions such as tomographic recon- struction and flexible display of images. As computer speed increases exponen- tially, and with memory and disk capacity showing similar growth, the capacity of the computer to tackle more complex and challenging tasks in a clinically acceptable time increases. Patient throughput and efficiency of operation are greatly aided by the computer tools available. By adopting these relatively highly developed and widely used computer systems, for which numerous hardware and software options are available, the vendors are now able to offer support for industry standards in several important areas, including networking.

The What makes the scientific method unique is that experimenter must record the raw data prior to any it does not accept an explanation as valid until it analysis and document any protocol deviations, has been validated through testing. A random phenom- mental finding inconsistent with a theory suggests enon is one where the outcome cannot be predicted that a theory should be revised or rejected. Experimental outcomes contradicting the an identical effect in the same patient under identi- theoretical predictions would lead to a reassess- cal conditions on separate occasions. That In other words, a scientific theory is always tenta- is, one can assign numerical values describing the tive and entirely dependent on experimental likelihood, or probability, of the possible outcomes. Similarly, an True state Decision isolated successful drug treatment outcome does Accept hypothesis Reject hypothesis not prove that the drug is efficacious. This substitution raises a host of conceptual then the smaller the probability that the observed issues beyond the scope of this discussion, except to difference is random, the higher the probability say that this approach has its opponents and is not that rejecting the hypothesis of no efficacy is cor- accepted by all statisticians. Let us illustrate the statistical method with an The key difference between the statistical example: method and the scientific method is that statistic- A pharmaceutical company has developed an ally, no matter how unlikely a result may be, it is antihypertensive drug that is theorized to lower not impossible. Thus, the simple experiment described Seemingly, therefore, whether a drug is efficacious above cannot be used to disprove the hypothesis or not is a dichotomy. Since blood pressure is naturally variable, drug in lowering diastolic blood pressure, then how do we know whether the difference in blood lack of efficacy corresponds to E 0. Positive effi- pressure before and after treatment is due to the cacy corresponds to E > 0, which contains a con- drug or to the natural randomness of blood pres- tinuum of possibilities depending on the strength of sure? Thus, the hypothesis of no efficacy is variability of diastolic blood pressure; and (b) de- very specific in terms of the size of the effect and termine whether the change in blood pressure is is called a simple hypothesis, while a hypothesis likely to result from natural variability. In drug testing, is measured in all subjects before treatment and the statistical experiment is designed to reject the at some time point when the drug effect should null hypothesisÐthe hypothesis that there is no be measurable if the drug is efficacious. Because rejection of due to the drug and to measure their magnitude, the null hypothesis enables one to make the scien- and to determine adverse effects related to the tific claim that the study was performed to prove, drug. When the result of a test is declared significant, giving a particular drug at a particular dose) causes the only error that could occur is type I error. The probability of a type I error is sufficient, since both A and B could be caused by called the significance level of the test and is de- an effect C. The alternative to the null tion can be established by conducting an experi- hypothesis, on the other hand, is typically a com- ment both when effect A is absent and when effect posite hypothesis. In our example, the power of In studying drug effects in humans, the con- the test at E 10 is the probability that the statis- trolled clinical trial is the preferred method to es- tical test would be significant if the effect of the drug tablish causality.

The third row gives the Another issue is that when the measurement of change (D) in diastolic pressure (row 1 minus row efficacy is variable, it is impossible to determine 2). Instead, we calcu- measure the blood pressure of an individual repeat- late the mean of the squares of the deviations about edly before and just after administering an antihy- the mean as a measure of variability. The variance is an average of measurements will be dispersed around different non-negative numbers and it is, therefore, always central values, the post-treatment lower than the a non-negative number. It does, though, give factor equal to the square root of the number of us an idea of the magnitude of the response to measurements used to calculatep the mean. This is because our conclusion izing the trial is the study protocol, the document that the drug is effective was based on the mean of defining the subjects eligible for inclusion in the 10 measurements rather than on a single measure- study, the study procedures and schedules. However, the method has the advantage a variety of characteristics that could influence that it guarantees a maximum balance in the their response to treatment. The method of allocat- ing subjects to treatment must make sure that the resulting treatment groups are balanced with re- Bias and Blinding spect to such factors. Statisticians routinely use data balance by using a systematic, non-random alloca- obtained from a sample to estimate a parameter of tion scheme that will force the balance. Thus, using different and Any non-random method inevitably involves a de- independent samples would result in different cision by the individual making the allocation. Furthermore, tends to overestimate the quantity of interest, and there might be some other variables which affect when it is negative, it tends to underestimate it. For the ognized as such at the time the study is planned, or purpose of our discussion, we will sometimes use are impossible to balance for logistical reasons.

The from subjects being selected to the different treat- requirement that each letter appears in the block ment groups in a way that creates an imbalance in as frequently as any of the other two letters implies one or more prognostic variables. The number of the investigator or other people who can influence such random blocks generated must be such that the enrollment of subjects into the trial, or a faulty the number of letters in the resulting string equals treatment allocation method. Subjects are then assigned sequentially to away from the enrolling investigator and place it in the treatment group corresponding to the next un- the hands of chance. Also, there are many parison of two oral drugs, one of which is a tablet other ways that are not affected by randomization and the other a capsule, each subject receive a in which the investigator can influence the trial tablet and a capsule, one of which contains the outcome. Often the mere expectation that the that would reveal the identity of the treatment, drug will have a therapeutic effect produces the either to the investigator or to the subject, or effect. Once bias is introduced, it is very difficult ments are masked from both the investigator and and sometimes impossible to adjust for it at the the subject, the trial is called double-blind.

It is also wise to identify calculated the mean of the combined group, we important prognostic variables and design the trial ignored the fact that the group consisted of two so as to stratify according to them. If one measures the effect example, if one wants to stratify by sex and race, of treatment by calculating the overall mean effect when sex has two categories (male and female) and in the population, although this mean represents an race four (White, Black, Hispanic and other), the estimate of the treatment effect in this population, number of strata is eight. Adding another variable it might be associated with a large measurement with three categories, such as disease severity (mild, error which could make it difficult to distinguish moderate, severe), will bring the number of strata the signal from the background noise. If one can data centers performing the randomization would identify a priori certain subgroups, or strata, in the have to manage 24 randomization tables for each study population that are more homogeneous with investigator, one for each stratum, which is utterly respect to the efficacy variable of interest in the impractical. For a study of moderate size of 100± trial, then by estimating the effect within each of 500 subjects, a large number of strata may mean these strata, and combining these estimates, one that some strata may contain very small number of may increase substantially the power of the analy- subjects, which complicates the statistical analysis sis because the noise masking the effect of interest is and its interpretation. It is well known, for example, that in In summary, stratification is a very useful tool multicenter trials the measured effect often differs for noise reduction, but it has its limitations. The study of the pharmaceutical effect of a drug is To take advantage of the block design, the treat- always done in reference to a population of pro- ments are compared within each block and then the spective patients, e.
