R软件R2WinBUGS程序包在网状Meta分析中的应用

Application of R2WinBUGS Package of R Sotware for Network Meta-Analysis

R软件是一个自由、免费及开放的统计软件,并具有强大的绘图功能,但其处理网状Meta分析数据的代码命令较为复杂,因此易错且不易掌握。WinBUGS软件是基于贝叶斯理论而开发的一款统计软件,具有强大的数据处理功能,在处理网状Meta分析数据时,代码编写易懂且操作方便,但对结果的绘图功能欠佳。为充分发挥R软件与WinBUGS软件各自的优势,开发者在R软件的基础上研发了R2WinBUGS程序包,构建了R软件与WinBUGS软件之间的"桥梁",使网状Meta分析的过程和结果处理方便快捷又美观。本文以实例操作的方式展示使用R软件R2WinBUGS程序包进行网状Meta分析的过程。

R Software is an open, free of use and charge statistical software which has a powerful graphic capability; however, it requires more complex codes and commands to perform network meta-analysis, which causes errors and difficulties in operation. WinBUGS software is based on Bayesian theory, which has a powerful data processing capability, and especially its codes are simple and easy to operate for dealing with network meta-analysis. However, its function of illustrating statistical results is very poor. In order to fully integrate the advantages of R software and WinBUGS software, an R2WinBUGS package based on R software has been developed which builds a “bridge” across two of them, making network meta-analysis process conveniently, quickly and result illustration more beautiful. In this article, we introduced how to use the R2WinBUGS package for performing network meta-analysis using examples.
