英文摘要目的:探讨工具变量方法在中医药实效研究中应用的可行性和注意事项。方法:首先从工具变量的基本准则和假设、模型的应用、工具变量估计量、弱工具变量4个方面简单介绍工具变量应用的方法,然后以一个实例说明工具变量应用的评估标准和注意事项。结果:工具变量方法是一种控制混杂效应的方法,但其应用需基于一系列的统计假设。结论:在评估医疗干预效益的研究中,工具变量方法虽可控制混杂效应,但其一般不作为首选分析方法,如何寻找合理有效的工具变量是中医药实效研究中应用的最大难题。; This paper was aimed to discuss the feasibility and attentions of application of instrumental variable (IV) methods in traditional Chinese medicine (TCM) outcome research. First, the application of IV was introduced, which included the basic principles and hypothesis, statistical model, estimator of IV and weak IV. Then, an example was given to illustrate the evaluation criteria and attentions of IV. The resultsshowed that IV method was proposed as a potential approach to the problems of confounding in statistics. But using IV methods should be based on a series of statistical hypotheses. It was concluded that the IV analysis was a method controlling confounding bias, but generally it was not chosen as the preferred analytical method. The issue of searching for valid and plausible IV seemed to be the biggest obstacle in the outcome of TCM researches.; 科学技术部国家“重大新药创制”基金资助项目(2012ZX09303-010-002)创新药物研究开发技术平台建设,负责人唐旭东;国家中医药管理局中医药行业科研专项基金资助项目(201107006)中医慢病临床科研体系及其成果转化应用模式研究,负责人张伯礼,刘保延,胡镜清。; 中国科技核心期刊(ISTIC); 10; 1972-1977
