"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

"The distinguishing feature of the Comprehensive Meta‐Analysis Software Programme from the other Meta‐Analysis Software Programmes is to be most practical and to be understandable easily. While using the programme the only thing should be done is to enter the necessary data into the data sheet and to click on the relevant buttons. That's all. No need to calculate the statistical formulas by hand to reach the effect sizes, anymore. I would like to send my special thanks to you and your team from Ankara University, Ankara‐Turkey, Sevgi Guney, MSc in ClinPsych, MAPS"
