"Comprehensive Meta‐Analysis software is like a magic wand. The simple and clear interface (like an Excel sheet) will guide you to do complicated meta‐analysis within only a few clicks. The comprehensive formats included in the software allow researchers to input the data in various ways. It provides clear outputs and high‐resolution graphs which can be imported to Microsoft Word. I especially love the feature that shows you the calculation steps so you can check whether you’ve run it correctly. It also provides advanced sub‐group analysis, moderator analysis, meta‐regression, and publication‐bias analysis. This software is a lifesaver! Meta‐analysis becomes very easy with the help of Comprehensive Meta‐Analysis. I am sure I will use this software for upcoming meta‐analyses in the future."

"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."
