"Comprehensive Meta‐Analysis is the premier program for conducting meta‐ analyses. It has incredible flexibility in including many different types of effect sizes and in converting between them in a single analysis. It is extremely user‐friendly and has brilliant graphical capabilities."

David P. Farrington - Institute of Criminology, Cambridge University

"CMA is very easy to use. That’s partly because of the manual and tutorial which take you through the analysis step by step. It’s also extremely versatile in terms of the type of input data it will accept (which is really valuable because with a meta‐analysis you have to take what data you can get). The output is comprehensive enough to permit you to interpret your effects, not merely report them."
