"Comprehensive meta‐analysis (CMA) is essential software for the meta‐analyst. Complex analyses can be conducted easily using this intuitive software. The support staff are always helpful and respond quickly when questions arise. I highly recommend CMA."

"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."
