简要总结
The aim of the study was to evaluate any possible associations between engagement and position of the fetal head and the outcome of labor in women with induced labor, and to compare the value of ultrasound measurements in predicting the time from induction to delivery and operative deliveries.

结局指标
主要结局
Vaginal Delivery in Induced Labors
时间窗: Time from induction of labor to delivery
The association between Bishop score, ultrasound assessed fetal station, ultrasound assessed cervical length, cervical posterior angle and a vaginal delivery was investigated using area under the ROC curves. Fetal station was assessed by ultrasound as the fetal head-perineum distance (HPD); which was measured by transperineal ultrasound imaging as the shortest distance from the outer bony limit of the fetal skull to the skin surface of the perineum.
