"We had no knowledge on meta‐analyses and were somewhat confused by the number of programs available. Most of them were not easy to use, not insightful and required a priori knowledge of metaanalyses statistics. There was one exception: Comprehensive Meta‐analysis. We downloaded the software and went through the easy‐to‐use tutorial. Within an hour we were performing our own metaanalysis! Our analysis was verified by our statistical department with excellent results, giving us further confidence to continue our analysis and resulting in an excellent paper in the top journal on pain research: Niesters et al., Do Sex Differences Exist in Opioid Analgesia? A Systematic Review and Meta‐ Analysis of Human Experimental and Clinical Studies. Pain, 2010, in press, doi:10.1016/j.pain.2010.06.012."

"I used Comprehensive Meta‐Analysis (CMA) to help me analyze research questions of my dissertation. Without CMA, I won't be able to complete 'two folders' of analysis on time. I would also like to thank the team of CMA to help me make clear problems I encountered. My dissertation earned the annual dissertation award of my school. I would like to share this honor with the CMA and Dr. Borenstein, a humorous and sincere scholar."
