样本量是为不匹配的病例对照(或队列)研究计算的，其中目标是优势比的区间估计。所使用的程序给出了对数赔率比的100%(1-α)%可信区间不会超过具有指定概率(1-γ)的指定宽度的最小样本量。给出了各种参数值选择的样本量表格。与已发表的以预期细胞计数为基础的方法有相当大的不同。
Sample sizes are calculated for unmatched case-control (or cohort) studies where the goal is interval estimation of the odds ratio. The procedure used gives the smallest sample size for which a 100(1-α)% confidence interval for the log odds ratio will not exceed a specified width with specified probability (1-γ). Tables of sample sizes for various choices of parameter values are presented. Considerable disagreement is found with a published method which has as its basis expected cell counts.
