Strategies for recognition and quantification of misclassification are presented. Misclassification occurs when a subject is placed in the wrong "exposure" or the wrong "outcome" category as a result of the failure of an index measurement to reflect exposure or disease accurately. Data from a Health Hazard Evaluation illustrate how misclassification may result in an unwarranted etiologic assumption. Data from a lung cancer screening program illustrate how misclassification may result in erroneous estimates of disease prevalence.
本文介绍了识别和量化错误分类的策略。当一个研究对象由于指标测量未能准确反映暴露或疾病情况而被归入错误的“暴露”或“结果”类别时，就会发生错误分类。一项健康危害评估的数据说明了错误分类如何可能导致不合理的病因假设。一项肺癌筛查项目的数据说明了错误分类如何可能导致对疾病患病率的错误估计。
