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.


"Comprehensive Meta‐Analysis software is like a magic wand. The simple and clear interface (like an Excel sheet) will guide you to do complicated meta‐analysis within only a few clicks. The comprehensive formats included in the software allow researchers to input the data in various ways. It provides clear outputs and high‐resolution graphs which can be imported to Microsoft Word. I especially love the feature that shows you the calculation steps so you can check whether you’ve run it correctly. It also provides advanced sub‐group analysis, moderator analysis, meta‐regression, and publication‐bias analysis. This software is a lifesaver! Meta‐analysis becomes very easy with the help of Comprehensive Meta‐Analysis. I am sure I will use this software for upcoming meta‐analyses in the future."

"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."
