Determination of significant relative risks and optimal sampling procedures in prospective and retrospective comparative studies of various sizes.

S D Walter.   

Abstract

Methods are given for determining the relative risks which it is possible to demonstrate as statistically significant with given probability in prospective and retrospective studies of a particular size. Also considered is the ratio of the sample sizes in the two groups being compared which will provide the most precise estimate of relative risk for a given total sample size.
