Objective To introduce the method of meta-analysis for effect combination of regression coefficient conducted with the metafor package in R software.
Methods By using the data of a published meta-analysis as an example, the detailed process of meta-analysis for regression coefficient was presented with metafor package in R.
Results The results of meta-analysis conducted with metaphor package in R were the same as the published literature.
Conclusion As a completely free open source software for statistical analysis, R can conduct meta-analysis for effect combination of regression coefficient flexibly and precisely, and should be expanded in the future meta-analysis.
