病例对照研究中存在的错误归类偏倚常使相对危险的估计值(OR)被夸大或缩小,从而对研究因素与疾病的联系估计错误。本文提出了对错误归类偏倚的调正方法及适用条件,并从理论上加以论证。
Misconceptions in Case-Control Studies Classification bias often overshoots or diminishes the relative risk estimates (ORs), thus making a false estimate of the link between research factors and illness. In this paper, we put forward a method of adjusting the bias of error classification and its application conditions, and theoretically prove it.
