aModels that showed the best sensitivity and an acceptable specificity in each study.

bPoint and interval estimates.

cAUC: area under the receiver operating characteristic (ROC) curve.

dCVR: classification via regression.

ePI-UtA: pulsatility index of the uterine artery.

fN/A: not applicable because it was not available.

gThis study showed an ROC curve without an AUC statement.

hFixed specificity in order to define sensitivity.

iThis study did not report an interval estimate.
