"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…!!!."

"Comprehensive Meta‐Analysis (CMA) is a must‐have tool for academic instructors, researchers, and statisticians alike. Developed by a strong team of highly recognized experts in the field, CMA meets all of your meta‐analysis needs and is easy to teach and easy to use. I would not attempt to ever conduct another meta‐analysis without using the CMA program, for the difference is between heaven and earth!"
