Prediction of duration of delivery mode
Survival analysis was used to predict the duration of delivery (in minutes) for the two groups. The duration was estimated from the beginning of induction to the time of delivery (whether vaginal or cesarean section). The results showed that the prediction of duration of vaginal delivery was 144.88 ± 99.25 minutes in the trans-labial plus the vaginal examination group and 432.99 ± 267.71 in the vaginal examination only group (P<0.01, Table Prediction of the duration of vaginal delivery (minutes) in the two study groups
