Sensitivity analysis
The findings showed that the sensitivity for prediction of vaginal birth with manual vaginal examination was 75.54% and by trans-labial ultrasound it was 91.6%. The results also showed that the data obtained from trans-labial ultrasound were more sensitive in predicting vaginal birth, especially in zero and positive stations (Tables Frequency distribution and partograph sensitivity of fetal head descending progression in trans-labial ultrasound plus vaginal examination groupFrequency distribution and partograph sensitivity of fetal head descending progression in vaginal examination only group
