Jagani 1984.

Methods	RCT.
Participants	47 women with intact membranes, Bishops score < 4.
Interventions	Control group vs IV oxytocin vs 1 mg vaginal PGE2. All groups had extra ovular catheter and if not in labour had ARM and oxytocin at 12 hours.
Outcomes	CS.
Notes	Randomisation based on case number. No measure taken to conceal the allocation. Extraovular catheter at low volume insufficient to act as co‐intervention.
Risk of bias
Bias	Authors' judgement	Support for judgement
Adequate sequence generation?	High risk	Case notes numbers.
Allocation concealment?	High risk	Allocation could be anticipated by investigators.
Blinding? Women	High risk	Not feasible, different interventions.
Blinding? clinical staff	High risk
Blinding? outcome assessor	High risk
Incomplete outcome data addressed? All outcomes	Unclear risk	Not all of the women were accounted for in all the results.
Free of other bias?	Unclear risk	Small study and results were difficult to interpret.
