"Comprehensive meta‐analysis (CMA) is essential software for the meta‐analyst. Complex analyses can be conducted easily using this intuitive software. The support staff are always helpful and respond quickly when questions arise. I highly recommend CMA."

"Since I bought Comprehensive Meta‐Analysis Version 2 about three years ago, it has become a faithful companion that is very easy to use, can be intuitively understood and offers all the options necessary for my meta‐analyses."
