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.
本文提出了一种计算方法，用于确定检测风险比所需的受试者数量，其中显著性水平（α）和检验效能（1-β）需预先设定。所考虑的风险比包括率比、比例比和比值比。该计算方法基于对数变换。
