Systematic reviews are key in practice of EBM and are to the peak of the evidence pyramid. In performing a systematic review/metaanalysis
and overview of systematic reviews, the evaluation of methodological quality of the included studies represents an important
step to identify poor quality studies that can give a falsification of effect's esteems. The aim of the present article is to analyze the
rating scales about methodological quality of observational studies, experimental studies, economic analysis, studies about diagnostic
tests and systematic review.
