"Comprehensive Meta-Analysis software is a user-friendly advanced program that assists researchers and academics to synthesize various and multiple primary studies on a specific area of interest. Also, a very well written book accompanies the software that guides even junior investigators step-by-step. Mathematics are well explained using simple language. It can be used as an encyclopedia for getting answers to every day questions. CMA outperforms any other software. It is a must-have and use for every researcher."

"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."
