摘要: 混杂偏倚是非随机化研究中偏倚一类的重要来源,对混杂因素的控制是研究中获得可靠结果的保证。本文简要介绍了在非随机化研究中常用的两类混杂控制方法——倾向性评分和孟德尔随机化,并对近年来国内相关研究现状进行综述,为倾向性评分匹配和孟德尔随机化的应用提供建议。Abstract: Confounding bias is a common source of bias in non-randomized studies, and the control of confounding factors is an important guarantee for reliable results. In this article, we briefly introduce two types of commonly used methods on confounding control: propensity scoring and Mendelian randomization. We reviewed the current research in recent years in China, with a view to provide recommendations for propensity score and Mendelian randomization research applications.
