Traffic light plot for the assessment of the risk of bias of each included randomized trial A and weighted plot for the assessment of the overall risk of bias B via the Cochrane RoB 2 tool (B) (n = 22 studies). Traffic light plot reports five risk of bias domains: D1, bias arising from the randomization process; D2, bias due to deviations from intended intervention; D3, bias due to missing outcome data; D4, bias in measurement of the outcome; D5, bias in selection of the reported result; green circle represents low risk of bias, yellow circle indicates some concerns on the risk of bias, red circle reports high risk of bias, and blue circle indicates insufficient information on the risk of bias.
