Suspected Fetal Growth Restriction at 37 Weeks: A Comparison of Doppler and Placental Pathology

Table 4

Performance of Doppler in prediction of placental pathology in suspected FGR.

Doppler	Sensitivity	Specificity	PPV	NPV
Any	55.1 (42.6, 67.1)	77.4 (58.9, 90.4)	84.5 (70.5, 93.5)	43.6 (30.3, 57.7)
Umbilical	17.4 (9.3, 28.4)	87.1 (70.2, 96.3)	75.0 (47.6, 92.7)	32.1 (22.4, 43.2)
MCA	52.1 (37.2, 66.7)	95.0 (75.1, 99.9)	96.2 (80.4, 99.9)	45.2 (29.9, 61.3)
Uterine	55.2 (35.7, 73.6)	80.0 (44.4, 97.5)	88.9 (65.3, 98.6)	38.1 (18.1, 61.6)

PPV = positive predictive value, NPV = negative predictive value, MCA = middle cerebral artery, and FGR = fetal growth restriction.
