to be significant. steroid discussion boards Effects of anabolic steriods. Or if we must use only 10 subjects per group, we would need to reduce their standard deviation to only about 1 lb. , by finding a set of people where gains would be similar for everyone unless Supplement X does something. Now back to the JAMA study. steroid discussion boards Steroid ratings. Criticism of MethodsConsultation with any expert would have resulted in these investigators finding out from the very beginning that their study could not be expected to discover any effects of AD unless those effects were quite large, and larger than anyone really was expecting. Having this information and being advised of how to overcome the problems, perhaps a useful study could have been performed, and we would have fairly accurate and precise measurements of the effects of AD. That, however, was not to be. steroid discussion boards Pictures of steroid abuse. What are the problems with the methods?Not only were only a small number of subjects selected but the variability of the subjects was (and could have been predicted to be) very high. As we saw in the above discussion, when both of these are the case, then only rather large effects can be found significant, and moderate effects that might well be very valuable simply cannot be discerned from the other variation. When the number of subjects is small, assignment to groups should not simply be random. If this is done, then it is quite possible (as happened in this study) that one group will consist of mostly fatter people than the other, or weaker people, or people with higher starting levels of testosterone, etc. Instead what should be done is that subjects should be paired, finding the most similar matches for each person, and then one member of the pair is assigned randomly to one of the two groups, and the other member to the other group. This results in groups that are much more similar to each other. This is standard procedure in the pharmaceutical industry for small-scale trials. Since the JAMA study failed to do this, their results are open to question. Would perhaps the AD group have done even better if they hadn't been the fatter and weaker group to start out with? Or, where the AD group outperformed the placebo group, was their initial weakness and fatness the sole cause of whatever difference was seen between the groups? We don't know. Obviously, this was a flaw in the study. Even if the authors did not wish to use the paired method, their statistician should have warned them that the randomization process yielded, by bad luck, groups substantially and significantly different from each other, and advised that the subjects should be re-randomized to yield groups that were not different from each other. Untrained individuals were used as subjects. If they had chosen selected trained athletes, drawing perhaps from the various athletic teams of their university, they would have been able to find subjects who had reached near steady-state results to their training, and who therefore would not show much variability in their gains.
