"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."

"I have used Comprehensive Meta‐Analysis II for the last 6 years to assist with a number of published meta‐analytic studies in the behavioral sciences. I have found the program to be flexible and powerful. I have also used CMA II in two graduate seminars focused on meta‐analysis. The students are able to learn the program quickly and appreciate how it structures their data sets and prevents some common mistakes made in meta‐analysis."
