Meta-analysis: Its strengths and limitations

open access: yesCleveland Clinic Journal of Medicine, 2008
Nowadays, doctors face an overwhelming amount of information, even in narrow areas of interest. In response, reviews designed to summarize the large volumes of information are frequently published. When a review is done systematically, following certain criteria, and the results are pooled and analyzed quantitatively, it is called a meta-analysis.
