"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

"Seeing that I can do with Comprehensive Meta‐analysis in 1 week what have taken me 3 weeks when I was using Excel spreadsheets for calculations I have the following: "Comprehensive Meta‐Analysis has increased my effectivity to do meta‐analysis with 200 %". I am extremely satisfied with this program."
