"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."

"Comprehensive Meta‐Analysis Version 2 is really an easy‐to‐use software. It offers you a broad range of statistical, analytical and graphic capabilities to ensure valid meta‐analysis. It is accompanied by a selfexplanatory manual and tutorial. For anyone considering a faster and complete performance of metaanalysis, this software would be a clear first choice. In addition, the book and the online course “Introduction to Meta‐analysis” have been ideal resources in my case, for a complete understanding of this approach. Both strongly recommendable…!!!."
