"I have conducted several meta‐analyses over the past several years, and Comprehensive Meta‐Analysis has been the main software I have relied on. It is "user friendly" and it provides a wide range of options to fit the different types of effect size information found in different types of studies. Most importantly, I know I can rely on the statistical formulas at the foundation of the software, due to the top‐notch development team for CMA."

Frank Pearson

"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"
