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.


"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."

"I have the pleasure to use your software from 2004, and thanks to that, my group had the opportunity to explore many issues in clinical oncology. I am a doctor (not a statistician) and I have to say that the software is really simple (especially v. 2.0), fast‐to‐use, and really easy to understand for anyone who wants to use it. We currently prefer CMA 2.0 to other free software given the mentioned features. Actually, I have no drawbacks to stress, I am really friendly in using your software right now."
