Comprehensive Meta-Analysis

Comprehensive Meta-Analysis (CMA) is a powerful computer program for meta-analysis. The program combines ease of use with a wide array of computational options and sophisticated graphics.


"One of the hardest things for non‐statisticians conducting meta‐analyses is to figure out how to combine data when the data are in different forms. Using continuous outcome as an example, one study might report before‐and‐after scores, and another might report change scores. Comprehensive Meta‐Analysis allows one to take data in any form and seamlessly converts it so that all the data can be included, or tells the meta‐analyst what additional information is necessary to complete the process. This one aspect of the program can save hours of time for non‐statisticians who are not used to converting data from one format to another."

"Comprehensive Meta‐Analysis (CMA) is an excellent statistical software program. CMA is very userfriendly, provides essential elements of analyses required for synthesis of quantitative studies, evaluates publication bias statistically and graphically, and offers technical support. I have used CMA for a recent study I conducted with my professor at the University of Maryland, The reliability and validity of the Anticipated Turnover Scale across studies of RNs in the US (in press). I highly recommend the Comprehensive Meta‐Analysis software program for anyone conducting meta‐analytic research."
