应用Stata软件实现观察性研究效应量及可信区间的Meta分析

Application of Stata software to conduct a meta-analysis with the effect value and its 95% confidence interval

大部分观察性研究的统计结果采用效应量及其95%可信区间(95%CI)表示,不符合传统Meta分析使用的数据格式。因此,使用Review Manager软件进行此种类型数据的Meta分析时,需要对数据进行特殊转换,使操作变得复杂、繁琐。Stata软件功能强大,能够直接应用效应量及其95%CI进行Meta分析,是进行观察性研究Meta分析必不可少的统计工具。本研究以已发表的Meta分析数据为例,主要介绍如何采用Stata软件实现效应量及其95%CI的Meta分析。

Most statistical data in observational studies is expressed as the effect value and its 95% confidence interval （95% CI）, which do not correspond to the data format used for traditional meta-analyses, so special data conversion is to be needed when Review Manager software is applied to do a meta-analysis for this type of data, which will make the operation complicated and cumbersome. In addition, Stata software is such a powerful statistical software that can be used directly to conduct a meta-analysis with the effect value and its 95% CI. Therefore, it is an indispensable statistical tool for meta-analysis in observational studies. And this study will give a brief introduction how to use Stata software to conduct a meta-analysis with effect value and its 95% CI based on the published meta-analysis data.
