Interventions	Low‐dose vaginal misoprostol: 25 mcg, repeated up to 6 doses every 4 hours. If no BS > 7 after 24 hours, oxytocin was started Foley catheter (n = 59) 18 F, 50 mL. After 12 hours oxytocin was started.

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Not reported how
Allocation concealment (selection bias)	Unclear risk	Not reported how
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	No ITT mentioned, no missing data, 1 woman excluded because of bad participation?
Selective reporting (reporting bias)	Unclear risk	Time to delivery: not clear from when till delivery, most likely from active phase. primary outcome was for first intervention to delivery. other pre‐specified outcomes reported
Other bias	Low risk	No other bias detected
