"Comprehensive meta‐analysis (CMA) is essential software for the meta‐analyst. Complex analyses can be conducted easily using this intuitive software. The support staff are always helpful and respond quickly when questions arise. I highly recommend CMA."

Erika A. Patall - Department of Educational Psychology, The University of Texas at Austin, Austin, TX

"CMA makes the complicated easy. I use it in my research, but in fact I've also used it in the clinic, to summarize evidence for treatment decisions."

Johan Sundström - Uppsala University Hospital, Sweden
