"I have used Comprehensive Meta‐Analysis for the past six years in my research activities. It has become a part of my research life. I use it for literature review, to compare and contrast differences in findings, and to search for insight in empirical studies. Comprehensive Meta‐Analysis helps me enhance my research productivity, efficiency, and quality."

"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"
