摘要 Meta分析是对原始研究的二次综合分析与评价,其质量受纳入原始研究质量、评价的方法、评价者的知识水平及观点的影响.若Meta分析纳入的原始研究质量低,且未对原始研究方法学质量进行正确评价,Meta分析的结果和结论可能是不正确的,从而对临床实践造成误导[1].因此,对Meta分析纳入的原始研究质量进行严格的评价尤为重要.原始研究质量评价工具主要根据研究设计、实施、结果分析整个过程中可能出现偏倚的各个因素而确定,目前出现的评价工具较多,主要有单个评价条目(components/items)、清单(checklist/list)和量表(scale)三种类型.前面我们已经对Meta分析的类型[2]、Meta分析的软件[3]进行了介绍,本文将在简要回顾原始研究类型的基础上,对随机对照试验(randomized controlled trail,RCT)常用的质量评价工具进行简要分析.
