Summary of findings 5. Oral mifepristone versus Foley catheter.

Oral mifepristone compared with Foley catheter for term labour induction for women with a previous caesarean section
Patient or population: pregnant women, 40 weeks' gestation, single cephalic presentation, 1 previous low segment caesarean section Setting: India, 2012‐2014 Intervention: oral mifepristone (400 mg) orally at 40 + 5. All women were reassessed 24 hours and 48 hours later. If BS > 6, amniotomy was performed, followed by oxytocin infusion. If after 48 hours, BS was < 6, induction of labour was done with oxytocin infusion Comparison: Foley catheter with 30 mL normal saline inserted at 40 + 5
Outcomes	Anticipated absolute effects* (95% CI)		Relative effect (95% CI)	№ of participants (studies)	Quality of the evidence (GRADE)	Comments
	Risk with mifepristone	Risk with Foley catheter
Vaginal delivery not achieved within 24 hours						not reported
Uterine hyperstimulation with fetal heart rate changes						not reported
Caesarean section						not reported
Serious neonatal morbidity or perinatal death						not reported
Serious maternal morbidity or death						not reported
*The risk in the intervention group (and its 95% confidence interval) is based on the assumed risk in the comparison group and the relative effect of the intervention (and its 95% CI). BS: Bishop score; CI: Confidence interval; RR: Risk ratio
GRADE Working Group grades of evidence High quality: we are very confident that the true effect lies close to that of the estimate of the effect Moderate quality: we are moderately confident in the effect estimate: the true effect is likely to be close to the estimate of the effect, but there is a possibility that it is substantially different Low quality: our confidence in the effect estimate is limited: the true effect may be substantially different from the estimate of the effect Very low quality: we have very little confidence in the effect estimate: the true effect is likely to be substantially different from the estimate of effect
