The second edition of this best-selling book has been thoroughly revised and expanded to reflect the significant changes and advances made in systematic reviewing. New features include discussion on the rationale, meta-analyses of prognostic and diagnostic studies and software, and the use of systematic reviews in practice.
A little dated at this point, but still an excellent primer. Not a lot of math or specifics on how to do. Great sense of what matters and why though. Adds a feel for the process if not arming the reader with a lot of how tos.
