Figure 3From: Screening models using multiple markers for early detection of late-onset preeclampsia in low-risk pregnancy Multivariate ROC curves for combination models. PAPP-A + sFlt-1/PlGF1, BMI + sFlt-11, and sFlt-1/PlGF1 + sFlt-1/PlGF2 were the best combinations for predicting preeclampsia. PAPP-A: pregnancy-associated plasma protein-A, sFlt-11: second trimester sFlt-1, sFlt-1/PlGF1: second trimester sFlt-1/PlGF ratio, sFlt-1/PlGF2: third trimester sFlt-1/PlGF ratio.Back to article page
