Figure 2From: Screening models using multiple markers for early detection of late-onset preeclampsia in low-risk pregnancy Univariate ROC curves for the second and third trimester sFlt-1/PlGF ratios. The second trimester sFlt-1/PlGF ratio (sFlt-1/PlGF1) and third trimester sFlt-1/PlGF ratio (sFlt-1/PlGF2) were the best markers for predicting preeclampsia.Back to article page
