Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Random assigned; not described how this was done. In trial registration => parallel assignment.
Allocation concealment (selection bias)	Unclear risk	Random assigned; not described how this was done. In trial registration => parallel assignment.
Blinding of participants and personnel (performance bias) All outcomes	Unclear risk	Not feasible due to nature of intervention
Blinding of outcome assessment (detection bias) All outcomes	Unclear risk	Not reported
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	ITT, no tables available, so incomplete data can not be judged, no missing data described
Selective reporting (reporting bias)	Low risk	All pre‐specified outcomes were reported in results
Other bias	Unclear risk	Full text is an accepted manuscript without tables, therefore risk of bias cannot properly be determined
