When results are classified in categories (for example, improved and unimproved, reactive and non-reactive) and the same patients are examined by two different treatments or two different tests, then the correct statistical analysis is by McNemars test. More often a Chi-square analysis is used; this is not only incorrect but also leads to erroneous conclusions.
当结果被分类(例如,改善和未改善、反应性和非反应性),并且相同的患者接受两种不同的治疗或两种不同的测试时,那么正确的统计分析是使用 McNemar 检验。更常见的是使用卡方分析;这不仅不正确,还会导致错误的结论。
