Vakhariya 1972.

Methods	Unclear method of randomisation.
Participants	100 multiparous women at 36‐43 weeks of gestation. Exclusion criteria were grand muliparity and previous caesarean section. Bishop score less than 6 was deemed a difficult induction.
Interventions	Oxytocin increasing to a maximum of 16 mU/min (n = 50) versus intravenous prostaglandin F2 alpha increasing to a maximum of 40 ug/minute (n = 50). Amniotomy was performed when possible (not specified).
Outcomes	Failure to deliver after 10 hours resulted in abandoning the procedure and discharge the following day.
Notes	A relatively high dosage regimen of prostaglandin F2 alpha is compared to a low dose regimen of oxytocin.
