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.


"CMA makes the complicated easy. I use it in my research, but in fact I've also used it in the clinic, to summarize evidence for treatment decisions."

Johan Sundström - Uppsala University Hospital, Sweden


"While I was looking for a computer program for meta‐analysis, I did a thorough search and compared all available programs I located. I decided to use CMA because of its versatility and authoritativeness. It allows me to code data of various formats and conduct all kinds of analysis – Q tests, meta‐regression, sensitivity analysis, etc. It also provides results associated with both the fixed‐effects and randomeffects models. Furthermore, the program is developed by a team of leading scholars in meta‐analysis. I feel lucky to be able to find a program through which I can draw on the expertise of so many outstanding experts."
