"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."

"Comprehensive meta‐analysis is so easy to use that a clinician feels absolutely comfortable with it. You only need to have the results from individual studies and follow instructions: you will have calculations and graphs in a way that you can easily interpret. With this software meta‐analysis is not arcane any more: if you can read papers based on this statistical technique you will be able to write them as well."
