Table 2 Comparison of maternal and fetal factors between women with normal vaginal delivery after induction of labor and those who were candidate for Cesarean section. Analysis of the mean difference of cervical length, Bishop Score and fetal head-pubis symphysis distance was performed with multivariate analysis with adjustment for body mass index

From: Pre-induction translabial ultrasound measurements in predicting mode of delivery compared to bishop score: a cross-sectional study
