"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."

"The program in Comparative Effectiveness and Outcomes Research at Duke University conducts multiple systematic reviews and meta‐analyses each year for professional organizations as well as under both federal and industry sponsored research initiatives. While we use various programs tailored for specific individual projects including those developed in‐house, we have found Comprehensive Meta‐Analysis (CMA) to be a very facile, adaptable and yet comprehensive package meeting the needs for much of our research and generating publication‐quality graphics. My confidence in the analytic algorithms is buoyed by my knowledge of several of the developers of CMA and based on extensive comparison of results with other algorithms including our own. CMA is also an exceptional educational tool and universally embraced by trainees and young investigators initiating careers in evidence‐based medicine and statistical analysis."
