Comprehensive Meta-Analysis

Comprehensive Meta-Analysis (CMA) is a powerful computer program for meta-analysis. The program combines ease of use with a wide array of computational options and sophisticated graphics.


"One of the hardest things for non‐statisticians conducting meta‐analyses is to figure out how to combine data when the data are in different forms. Using continuous outcome as an example, one study might report before‐and‐after scores, and another might report change scores. Comprehensive Meta‐Analysis allows one to take data in any form and seamlessly converts it so that all the data can be included, or tells the meta‐analyst what additional information is necessary to complete the process. This one aspect of the program can save hours of time for non‐statisticians who are not used to converting data from one format to another."

"I have been a satisfied user of Comprehensive Meta‐Analysis software for about two years. I find the software is easy to use and offers an extensive range of options for analysis. I like being able to toggle between fixed and random effects, and seeing the difference(s) between the two. I also find that the ability to evaluate symmetrical confidence intervals, and have non‐symmetry flagged, is a major advantage to the software. The automatic generation of funnel plots, which do not exist as an option in many scientific graphing packages, is particularly of value when discussing bias."
