[Calculation of sample size for the detection of relative risk with a predetermined confidence level and power].
Herein, a method of calculation is proposed for determining the number of subjects required for risk ratio detection, the significance level (alpha) and the power (1 - beta) being fixed in advance. Risk ratios under consideration are rate ratios, proportion ratios and odds ratios. The method of calculation is based on the logarithmic transformation.
