Uterine artery (UT) Doppler velocimetry was defined as abnormal if the mean RI was >95th percentile for gestational age. Umbilical artery (UA) Doppler velocimetry was defined as abnormal if either the PI >95th percentile for gestational age or if absent or reversed end-diastolic velocity was present.
