Risk of bias assessment. The risk of confounding bias was considered to be high (red) if the confounder was not reported or reported but imbalanced among the treatment groups without any adjustment in the statistical analysis. Alternatively, the risk of confounding bias was considered to be low (green) if the confounder was reported and balanced among the treatment groups or imbalanced but adjusted for in the statistical analysis. a=random sequence generation (selection bias); b=allocation concealment (selection bias); c=blinding of participants and personnel (performance bias); d=blinding of outcome assessment (detection bias); e=incomplete outcome data (attrition bias); f=selective reporting (reporting bias); g=other bias.
