A Completion of vaginal delivery for different instrumental delivery methods. Data are present as raw and adjusted odds ratio with Keilland’s forceps delivery as referent group. * Adjusted for maternal BMI, birth weight, parity, analgesia, experience of deliverer, fetal position and fetal station.
B Immediate perinatal adverse outcome following all delivery modes. Data are present as raw and adjusted odds ratio with pEmCS delivery as referent group. ** Adjusted for maternal BMI, birth weight, analgesia, experience of trial decision maker, indication for trial, experience of deliverer, fetal position and fetal station.

A Relationship between delivery mode and completed vaginal delivery - adjusted for maternal BMI, birth weight, parity, analgesia, experience of deliverer, fetal position and fetal station. AUC. 0.768 (Std Error 0.025)
B Relationship between delivery mode and overall composite risk score - adjusted for maternal BMI, birth weight, analgesia, experience of trial decision maker, indication for trial, experience of deliverer, fetal position and fetal station. AUC 0.642 (Std Error 0.024)
