Methods	"The women were randomly allocated". The sequence generation and the allocation concealment were not stated.
Participants	Inclusion criteria: singleton pregnancy, vertex presentation, Bishop score < 5 and intact membranes. Exclusion criteria: multiple pregnancy, parity > 4, breech presentation, previous uterine scar, hypersensibility to prostaglandins, probable cephalopelvic disproportion, vaginal bleeding in second pattern and vaginal or cervical infection.
Interventions	The intervention group received 50 mcg vaginal misoprostol repeated if no cervical ripening after 6 hours. The comparison group received 0.5 mg intracervical dinoprostone repeated after 12 hours if necessary. Both groups could use oxytocin augmentation.
Outcomes	There were no differences between the groups in time interval from induction to delivery, in the incidence of tachysystole, hypersystole and caesarean section rate. The incidence of delivery before 12 hours was higher in the misoprostol group (p < 0.02).
Notes	The study was carried from January to April 2002. Rajah Muthaih Medical College and Hospital, Annamalai University, Tamil Nadu.
