Evaluation of the methodological quality of the included trials. (A) Individual risk of bias assessment for each selected study, based on the Rob tool. (B) Overall risk of bias summarized as a percentage, considering intention-to-treat and per-protocol analyses. The primary sources of high risk of bias across the studies were deviations from intended interventions, followed by issues related to missing outcome data and deficiencies in the randomization process [2,3,15,17,34,35,36,37,38].
