Methods for Including Information from Multi-Arm Trials in Pairwise Meta-Analysis
Rücker, Gerta; Cates, Christopher J.; Schwarzer, Guido
Research Synthesis Methods, v8 n4 p392-403 Dec 2017
Systematic reviewers conducting pairwise meta-analyses sometimes encounter multi-arm studies. To include these studies, and to avoid a unit-of-analysis error, often two or more arms are combined or the control arm is split. In this tutorial, we present 5 different approaches that can be used. Particularly, we present a novel approach (method 4) that to the best of our knowledge has not been presented before. We demonstrate their application on 3 selected data sets, discuss their scope of application and their advantages and limitations, and give recommendations.
