Obstacles in evaluating small effects,or example, to be able to demonstrate a relative risk of 5 in the context of a case-control study in which the prevalence of exposure is about five per cent, only seventy cases and seventy controls are needed. On the other hand, if the relative risk one is interested in is 1.1, about 35,000 cases an

Proposals and recommendations concerning small effects in case-control and cohort studies,e, an absolute estimate or absolute statement on risk ratio levels in relation to causal inference cannot be made. I cannot share his point. It does not seem logical to me. The existence of false negative and false positive results in low risk associations does not prove that there is no formal rela

Research strategies for assessing epidemiolgic associations, in relation to the distribution and merom effects that are small by virtue of study design and execution. In the former situation there is little variation in disease risk across the exposure levels that are within the range of common human experience and it follows that only a small fraction of current human disease burden can be attri
