Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Randomisation process unclear
Allocation concealment (selection bias)	Unclear risk	Unclear
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	High risk	Unclear if ITT analyses was used. for CS there are missing cases
Selective reporting (reporting bias)	High risk	Only primary outcomes were reported in trial registration
Other bias	Unclear risk	Study was terminated (not clear why)
