Zahoor 2014.

Methods	RCT
Participants	Women requiring IOL for common indications, no previous CS
Interventions	PGE2 tablets (n = 100) dosage of 2 mg, every 6 hours, max of 4 doses transcervical balloon catheter(n = 100) filled with 60 mL of saline.
Outcomes	Induction to delivery interval, mode of delivery, meconium staining, CTG abnormalities, admission in NICU, low AS
Notes	No relevant outcomes were reported in the abstract Setting: Pakistan Study period: not reported Funding: not reported Declarations of interest: not reported
Risk of bias
Bias	Authors' judgement	Support for judgement
Random sequence generation (selection bias)	Unclear risk	Randomisation not described
Allocation concealment (selection bias)	Unclear risk	No information
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	No information
Incomplete outcome data (attrition bias) All outcomes	Unclear risk	ITT not reported, insufficient information.
Selective reporting (reporting bias)	Unclear risk	Insufficient information.
Other bias	Unclear risk	Abstract only, too little information to judge risk of bias
