Comprehensive Meta-Analysis

software image

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.


"I have been using Comprehensive Meta‐Analysis for more than three years and have finished a dozen meta‐analyses with this software. The biggest advantage is that it’s easy to perform and manage the analysis. Studies can be added or removed from the analysis without modifying the data. There are a variety of effect‐size measures, including treatment difference, odds ratios, rate differences, correlations, etc. The diagnosis and transformation of the effect size is just one click away. The highquality forest plot and comprehensive meta‐regression distinguished this software from others."

"CMA is a formidable tool for conducting sophisticated meta‐analyses in the domain of cognitive and behavioral sciences. As an early adapter of CMA I am still amazed about its flexibility in data storing, data processing, and its many options for validity checks of meta‐analytic outcomes such as trim‐and‐fill and other state‐of‐the‐art ways to test the influence of unpublished papers. The flexibility of CMA to exchange data with Excel, SPSS, and other statistical software is a major asset. I also taught courses on meta‐analysis with the student version of CMA available for the graduate students, and it has been a real success as CMA makes meta‐analysis transparent as well as motivating for students with a basic training in statistics."
