"CMA is very easy to use. That’s partly because of the manual and tutorial which take you through the analysis step by step. It’s also extremely versatile in terms of the type of input data it will accept (which is really valuable because with a meta‐analysis you have to take what data you can get). The output is comprehensive enough to permit you to interpret your effects, not merely report them."

Dr. Marie Blackmore - Research Coordinator, The Centre for Cerebral Palsy, Mount Lawley, WA, Australia

"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!"
