"Comprehensive Meta‐Analysis v.2 is the definitive leading software for computing, presenting and analysing results of meta‐analyses. The programme provides beginners as well as advanced researchers meta‐analysis opportunities, unmatched by competing programmes. Computing effect sizes, combining across various types of outcomes, conducting moderators analyses, and presenting these rather complex analyses in less than five stages, could not have been more user‐friendly."

"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."
