Stenlund 1999.

Methods	RCT, 2 arm trial.
Participants	Setting: 36 women attending hospital in Stockholm, Sweden. Inclusion criteria: maternal or fetal indications for labour induction, women in whom labour induction could be deferred for 48 h, Bishop score < 6, single pregnancy, head presentation and intact membranes. All women were 14 days post‐term and scheduled for induction, but where IOL could be postponed for 48 h. Exclusion criteria: parity > 4, contra‐indications to vaginal birth, oligohydramnios, prior uterine surgery, obstetric or medical complications.
Interventions	Intervention group: 400 mg mifepristone. Comparison group: placebo. Women returned for review after 24 h and 48 h if labour did not start. If Bishop score > 6 then ARM and oxytocin induction, if < 6 then PGE₂ 0.5 mg intracervical up to 2 treatments.
Outcomes	Labour within 48 h, Mode of onset of labour, ripe cervix within 48 h, birth within 48 h, need for PGE₂ for cervical ripening, change in Bishop score, duration of labour, interval from treatment to admission in labour, Apgar score, umbilical pH, maternal and neonatal serum concentrations of mifepristone at birth.
Notes
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Low risk	Random number tables.
Allocation concealment (selection bias)	Low risk	Coded drug boxes, "sealed pre‐numbered boxes containing either mifepristone or placebo tablets".
Blinding (performance bias and detection bias) Women	Low risk	"...the type of treatment the women were given was not known until the entire study was finished".
Blinding (performance bias and detection bias) Clinical staff	Low risk	Study described as blinded.
Blinding (performance bias and detection bias) Outcome assessor	Low risk	Study described as blinded.
Incomplete outcome data (attrition bias) All outcomes	Low risk	No losses to follow up apparent.
Selective reporting (reporting bias)	Unclear risk	Many more outcomes reported than mentioned in methods text. FHR and uterine contractility not mentioned specifically in results text.
Other bias	Unclear risk	Some baseline imbalance, intervention group 79% primiparous versus 58% in the control group.
