Methods	RCT
Participants	Inclusion: singleton pregnancy, cephalic, cervix unfavourable (MBS < 6), 40 weeks and 6 days Exclusion: multiple pregnancies, malpresentation, previous CS or any contraindication for normal delivery or misoprostol, prior intervention for ripening of the cervix, non‐reactive CTG after fetal acoustic stimulation test.
Interventions	Oral misoprostol (n = 74) 25 ug, every 4 hours, max of 2 gifts Foley catheter (n = 78) max 24 hours
Outcomes	Modified BS ≥ 6 day 2 after the intervention; Induction to delivery interval, mode of delivery, side effects of misoprostol (only reported in trial register)

Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Computer‐generated sequence, block randomisation, stratified for parity
Allocation concealment (selection bias)	Low risk	Sequentially‐numbered opaque, sealed 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	ITT not mentioned, no FIgure 1, cases excluded for some selective outcomes because of spontaneous labour after intervention, no missing data reported.
Selective reporting (reporting bias)	Low risk	All pre‐specified outcomes were reported in results, except secondary outcome 'side effects misoprostol' not reported.
Other bias	Low risk	No other bias detected
