Methods	RCT
Participants	Inclusion: full‐term singleton gestation, cephalic presentation, indication for IOL. BS < 6. Exclusion: rupture of membranes, antepartum bleeding, placenta praevia, previous induction or pre‐induction agent during the pregnancy.
Interventions	Foley catheter (n = 50): 16 F with 30 mL balloon, traction applied. no max hours described. Misoprostol vaginal (n = 54): 25 ug post fornix, every 4 hours max 8 doses. Dinoprostone vaginal gel (n = 52), 2 mg, once every 6 hours, max of 3 doses
Outcomes	Change in BS, total time for induction, delivery route, uterine tachysystole (defined as 6 contractions in 10 minutes, in 2 consecutive 10 minutes periods), uterine hypertonus (contraction lasting longer than 3 minutes), subject comfort as women were asked to evaluate their discomfort on a visual scale from 0 to 10.

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated random allocation numbers
Allocation concealment (selection bias)	Low risk	Consecutive, opaque envelopes
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	As treated analysis (2 or 4 exclusions? (158 cases analysed, but total of included patients makes 156) Primary outcome: unclear how many women in Foley were analysed, in comparison groups 4 cases missing without explanation
Selective reporting (reporting bias)	Low risk	All pre‐specified outcomes were reported in results
Other bias	Low risk	No other bias detected
