Prediction of labour duration and vaginal delivery. a Prediction of labour duration >24 hrs by Bishop score vs cervical resistivity with 12 mm probe. ROC curve showing prediction of duration of labour >24 hrs by Bishop score assessment vs cervical resistivity obtained with a 12 mm probe (the AUC was significantly > than the area under the nondiagnostic line). b: Prediction of vaginal delivery by Bishop score vs cervical resistivity with 12 mm probe. ROC curve showing prediction of vaginal delivery by Bishop score assessment vs cervical resistivity obtained with a 12 mm probe. Only the AUC for CR 9.8 to 78.1 kHz was predictive of vaginal delivery (significantly greater than the nondiagnostic line, P < 0.01).
