Further, based on the ROC curve, abnormal Doppler (reduced flow, AEDF or REDF) had a sensitivity of 80% and specificity of 92.
11] retrospectively investigated the screening efficacy of UA S/D, PI, and AEDF for adverse pregnancy outcomes and placental abnormalities in SGA fetuses.
3%) for abnormal Doppler (reduced flow, AEDF or REDF) as a screening tool for detection of abnormal placental pathology.
Out of 30 patients studied between 32-33+6days of gestation, three had AEDF and 5 had CPR ratio <1.
Of the 25 cases, one patient had AEDF and 3 patients had CPR ratio<1.
Of the remaining 13 cases, one patient with AEDF and four patients with CPR of less than 1.
Pregnancies which showed abnormal doppler such as AEDF and CPR less than 1.
