"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."

Barak Ariel - UK

"Comprehensive meta‐analysis has been an easy to learn and reliable program that was my primary tool in conducting and publishing two large meta‐analyses in high impact factor peer reviewed journals."
