Summary of Findings Of the ten included systematic reviews, only two achieved a total rating of >50%) using AMSTAR 2. A small proportion of the reviews (20%) provided the protocol or registered information and explained selection inclusion of the study designs in the review. A comprehensive literature search was performed in one (10%) review, whereas others 9 (90%) did not provide a reason for each excluded study during full-text screening. Seven (70%) reviews performed study selection and data extraction in duplicate. Six (60%) reviews provided partial characteristics of study without the description of follow-up. Over 30% of reviews did not use a satisfactory technique for assessing the risk of bias in individual studies included in the review. None of the included reviews reported the source of research funding for randomized trials included in the systematic reviews. Nine (90%) reviews applied appropriate methods for statistical synthesis. Four (40%) reviews assessed the potential impact of risk of bias in individual studies on the results of the synthesis and accounted for risk of bias in individual studies when interpreting/discussing the results of the review, respectively. The potential conflicts of interest were reported in two (20%) reviews.
