摘要
R软件pcnetmeta程序包是一款基于贝叶斯理论实现网状Meta分析的程序包,其融合了JAGS软件的优势计算功能与R软件特有的数据整合和强大的图形绘制等功能。pcnetmeta程序包通过调用JAGS软件来实现运算,提供了3种不同模型供操作者选取,每种模型均给出3种不同的效应量(RR、OR及RD)结果;同时可以绘制多种图形,极大程度上满足了使用者处理复杂网状Meta分析的客观需求。本文以实例方式展现该程序包的完整操作流程。
The pcnetmeta package in R is a special package for performing network meta-analysis based on Bayesian theory, which combines the strength computing function of JAGS software and the special data integration and powerful graph drawing function of R software. This package conducts calculation by ca/ling JAGS, provides 3 different models for users, and each model can yield results of 3 effect-sizes （RR, OR and RD）. At the same time, this package can draw many kinds of plots, which greatly meets actual needs of users to deal with complicated network meta-analysis. In this article, we introduce how to use pcnetmeta package to perform network meta-analysis based on an example,
