Table 4. Areas under the curves (AUC), sensitivity and specificity of second trimester uterine artery PI for prediction of preeclampsia.

Markers	AUC (95% CI)	Sensitivity	Specificity
Uterine artery PI	0.836 (0.765 to 0.892)	97.73	73
PGF+ ADMA	0.902(0.837 to 0.946)*	95.45	85.39

*P = 0.12 compared with AUC of uterine artery PI.

PGF: placental growth factor; ADMA: asymmetric dimethylarginine; PI: pulsatility index; AUC: area under the curve; 95%CI: 95% confidence interval.
