Selection criteria: the selection criteria of a review define the study designs for both inclusion and exclusion. Likewise, overviews require assessment of the quality of evidence;9 however, the tools used in the overviews must be compatible with the study design used in the primary studies, which in this case may differ from clinical interventions.
