Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Generation of allocation sequence was not described
Allocation concealment (selection bias)	Unclear risk	Whether the treatment assignment was concealed from study personnel and participants was not described
Blinding of participants and personnel (performance bias) All outcomes	High risk	Owing to the nature of the intervention, it was not possible to conceal allocation to the intervention from the participants
Blinding of outcome assessment (detection bias) All outcomes	High risk	Study personnel and outcome assessors were not masked or blinded to the study interventions
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	Insufficient details provided to determine whether there was any attrition
Selective reporting (reporting bias)	Unclear risk	Insufficient details provided to assess whether there was selective outcome reporting
Other bias	Low risk	The trial appears to be free of other problems that could put it at a high risk of bias
