Quality Assessment
Pairs of reviewers (MB, PAT; LM, PAT) critically appraised quality using the Measurement Tool to Assess Systematic Reviews version 2 (AMSTAR-2)18 and the Critical Appraisal Checklist for Case Series of the Joanna Briggs Institute.19 Risk of bias in original studies was assessed with the Cochrane tool for RCTs (RoB2)20 and the risk of bias in non-randomized studies of interventions (ROBINS-I) tool21 for cohort studies.
Any disagreements on eligibility, extracted data or quality were resolved through discussion between reviewers and on consultation with a senior reviewer when necessary.
