"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."

"CMA has been a huge asset in my research on motivation and self‐regulation. I have used this software to conduct multiple meta‐analyses, each requiring different and multiple formats of effect size. CMA surpassed my needs and expectations every time. The software is really "comprehensive" yet exceptionally user‐friendly. Fellows and students have learned to use it in just one sitting. I highly recommend CMA to any researcher wishing to conduct meta‐analysis in a highly effective and efficient manner."
