Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Random assigned, no more information reported
Allocation concealment (selection bias)	Unclear risk	Not reported
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	No ITT reported, cases missing in table 2, not clear why
Selective reporting (reporting bias)	High risk	No outcome measures were mentioned in the method section, induction to delivery interval is given but no SDs,
Other bias	Low risk	No other bias detected
