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.
