The efficacy of different ultrasound Doppler parameters in predicting adverse fetal outcomes in pregnancies with hypertensive disorders: a systematic review and meta-analysis

In patients with HDP, abnormal UA PI, and CPR are risk factors for multiple adverse fetal outcomes. Additionally, for LBW, abnormal UA PI is associated with a higher risk than is abnormal CPR, while for FGR, abnormal UtA RI/presence of a uterine artery diastolic notch and abnormal UtA PI are associated with higher risks than are UA AREDF.
