"I have the pleasure to use your software from 2004, and thanks to that, my group had the opportunity to explore many issues in clinical oncology. I am a doctor (not a statistician) and I have to say that the software is really simple (especially v. 2.0), fast‐to‐use, and really easy to understand for anyone who wants to use it. We currently prefer CMA 2.0 to other free software given the mentioned features. Actually, I have no drawbacks to stress, I am really friendly in using your software right now."

"I recently used Comprehensive Meta‐Analysis on a large and complex data set involving several different outcome variables, several different research designs, and hundreds of effect sizes. I found the program easy to use and very powerful. Moderator analyses were easy to conduct, as were examinations of potential publication/selection biases. The user interface is intuitive and easy to navigate. It is a wonderful tool!"
