Two modifications are made in Schlesselman's procedure for determining the total number of pairs to be studied in a case-control study with matching. One is to take account of the use of the continuity correction in the McNemar test statistic, and the other is to incorporate a measure of the degree of association induced by the matching variables between a case's exposure status and that of his or her matched control. The result of both modifications is to increase the required number of pairs above the number produced by Schlesselman's procedure.
在施莱塞尔曼用于确定匹配病例对照研究中待研究的配对总数的方法上进行了两项修改。一是考虑在麦克尼马尔检验统计量中使用连续性校正，另一是纳入匹配变量在病例的暴露状态与其匹配对照的暴露状态之间所诱导的关联程度的一种度量。两项修改的结果都是使所需的配对数高于施莱塞尔曼方法所产生的配对数。
