Quality Assessment
The Cochrane Collaboration’s risk of bias tool was utilized to assess
the methodological quality of the included trials. Two investigators
separately conducted the quality assessment. In the event of
disagreements during the screening and evaluation process, the issue was
discussed, mediated upon and resolved with the help of a third party.
The risk of bias for every item was classified as low, high, and unclear
in accordance with the Cochrane Handbook for systematic Reviews.
