You can also rename this subgroup by repeating step 2 above.Ĥ. This time, select the ‘ Add Subgroup‘ option. To add more subgroups, click on the outcome name again and right-click. You can rename this by right-clicking on the new name and selecting the ‘ Rename Subgroup‘ option.ģ. Since only one subgroup is present, all of the included studies in the outcome will now be under this new subgroup. A new subgroup should now be included below the outcome in the tree view. Then, select the ‘ Introduce Subgroup‘ option.Ģ. In the tree view on the left-hand side, highlight the outcome and right-click it. To create subgroups in RevMan, simply follow the steps below.ġ. In other words, does the meta-analysis suggest there may be a sex effect? Creating subgroups in RevMan For the subgroup analysis, I want to see if the overall effect is different in those studies containing only females and only males. Specifically, I have 10 included studies which have measured the concentration of a protein in the blood of young and old adults. In this guide, I will use the same example dataset as the previous entering data into RevMan article. For example, comparing studies that involved only females and only males, or comparing studies which measured the effect estimate using method X and method Y. Specifically, studies can be split into separate groups based on a common factor. Subgroup analysis is a useful way of investigating heterogeneous results in a meta-analysis. This follows on from the guide to setting up and entering data into RevMan.
#COMPREHENSIVE META ANALYSIS SUBGROUPS HOW TO#
In this tutorial, I will show you how to create subgroups in a RevMan sheet which will be useful when performing subgroup analysis in a meta-analysis.
