"We bought the CMA software for professional perpetual version at the beginning of this year, and we have used it to do meta-analyses for several studies and trained the postgraduate students already. The friendly spreadsheet, easy-understandable dialog, not programming and modifiable output style make use of the software to do a meta-analysis convenient. The most fabulous point is that it can extend the traditional comparison of two groups to estimation of effect size in one group and generic point estimates. In summary, this software is an efficient and user-friendly tool for scientists to do a study related to meta-analysis."

"I have been a satisfied user of Comprehensive Meta‐Analysis software for about two years. I find the software is easy to use and offers an extensive range of options for analysis. I like being able to toggle between fixed and random effects, and seeing the difference(s) between the two. I also find that the ability to evaluate symmetrical confidence intervals, and have non‐symmetry flagged, is a major advantage to the software. The automatic generation of funnel plots, which do not exist as an option in many scientific graphing packages, is particularly of value when discussing bias."
