Valadan 2005.

Methods	RCT.
Participants	91 women attending for induction indicated by post‐dates. Inclusion criteria: singleton pregancy, cephalic presentation, intact membranes on admission, aged 16‐45 years, reassuring FHR, no more than 2 contactions in a 10‐minute period, Bishop score < or = 4. Exclusion criteria: uterine scar after previous C/S, contraindication to vaginal delivery, vaginal bleeding, ruptured membranes, unstable pre‐eclampsia, suspected chorionamnionitis, contraindication to prostaglandin.
Interventions	Both groups had routine amniotomy as early as possible after admission. IV oxytocin. 6 mU/min increasing by 6 mU/min at 40 min intervals to max dose of 42 mU/min, unless signs of fetal distress or hyperstimulation vs intravaginal dinoprostone (PGE2) tablet. After 6 hrs Bishop score evaluated if less than 3 contractions per 10 mins then IV oxytocin started at same dose as above.
Outcomes	Primary outcome: delivery within 24 hrs.
Notes	Mean length of labour stated but not clear how many women delivered within 24 hours.
Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	Unclear risk	Described as "stratified randomisation technique".
Allocation concealment?	Unclear risk	Not stated.
Blinding? Women	High risk	Not feasible.
Blinding? clinical staff	High risk
Blinding? outcome assessor	High risk
Incomplete outcome data addressed? All outcomes	Low risk
Free of selective reporting?	Unclear risk	Not clear how many women delivered within 24 hours (this was stated as the primary outcome).
