本文介绍了3种特殊检验的基本概念和所需样本含量估计方法,即非劣效性检验(主要目的为检验试验药的疗效在临床上不比阳性对照药差)、等效性检验(主要目的为检验两种药物的疗效在临床上是否等效)和优效性检验(主要目的为检验试验药的疗效在临床上优于对照药).本文还通过具体的实例,详细介绍了进行前述3种特殊检验所对应的试验研究之前所需要的样本含量的计算公式和用SAS实现计算的方法.

This article introduces definitions of three special tests,namely,non-inferiority test (to verify that the efficacy of the experimental drug is clinically not inferior to that of the positive control drug),equivalence test (to verify that the efficacy of the experimental drug is equivalent to that of the control drug) and superiority test (to verify that the efficacy of the experimental drug is superior to that of the control drug),and methods of sample size estimation under the three different conditions.By specific examples,the article introduces formulas of sample size estimation for the three special tests,and their SAS realization in detail.
