"I was interested in learning how to do a systematic review and meta‐analysis. I've done several courses but couldn't evolve to a complete analysis due to the limitations of available software. Then I became aware of "Comprehensive Meta‐Analysis". The program is very intuitive and the book "Introduction to Meta‐Analysis" is the most objective I've ever read in this topic. I have recommended to those interested in starting training in systematic review to begin by this book and software."

"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!"
