Table 3 AUC curves of different PE risks with the best fit cut-off values

From: Early prediction of preeclampsia and small-for-gestational-age via multi-marker model in Chinese pregnancies: a prospective screening study

  Type of risk AUC, 95%CI cut-off value DR%, 95CI FPR%, 95CI
Early PE Prior Risk 0.509 (0.491–0.526) 1:54 25 (3.2–65.1) 0.31 (0.1–0.6)
Posterior Risk 0.901 (0.890–0.911)* 1:45 87.5 (47.3–99.7) 3.94 (3.3–4.7)
Late PE Prior Risk 0.762 (0.747–0.776) 1:102 48.57 (31.4–66.0) 9.05 (8.1–10.1)
Posterior Risk 0.828 (0.814–0.840) 1:151 80.00 (63.1–91.6) 25.81 (24.3–27.4)
  1. AUC = Area under the receiver operating characteristics curve, DR = Detection rate, FPR = False positive rate, 95% CI = 95% Confidence interval. Cut-off values of different risks are at the highest average of sensitivity and specificity, and DRs and FPRs are shown at the best fit cut-off value of each type of risk. Pairwise comparison of ROC curves between prior risk and posterior risk in early PE and late PE individually, and significance level: * P < 0.05
