Abstract
This paper is a compendium of exact and asymptotic formulae and tables for estimating the sample size in a clinical trial with two treatment groups and a dichotomous outcome. The paper provides separate formulae for equal and unequal treatment group sizes, formulae for the calculation of power given the sample size, and complete references for all formulae and tables cited.
摘要
本文是一份关于在有两个治疗组和二分结局的临床试验中估计样本量的精确公式、渐近公式及表格的汇编。本文针对治疗组大小相等和不相等的情况分别给出了公式，给出了在已知样本量时计算检验效能的公式，并为所引用的所有公式和表格提供了完整的参考文献。
