ROC curve analysis

(A) Relationship between the sFLT1/PlGF ratio at 28 weeks of gestational age and the risk of pre-eclampsia with delivery of a preterm small for gestational age infant (birthweight below the tenth customised percentile; n=12 cases). (B) Relationship between the sFLT1/PlGF ratio at 28 weeks of gestational age and the risk of pre-eclampsia with delivery of a preterm non-small for gestational age infant (birthweight at or above the tenth customised percentile; n=14 cases). (C) Relationship between the sFLT1/PlGF ratio at 36 weeks of gestational age and the risk of pre-eclampsia with delivery of a small for gestational age infant (birthweight below the tenth population-based percentile; n=21 cases). (D) Relationship between the sFLT1/PlGF ratio at 36 weeks of gestational age and the risk of pre-eclampsia with delivery of a non-small for gestational age infant (birthweight at or above the tenth population-based percentile; n=203 cases). ROC=receiver operating characteristic. sFLT1=soluble fms-like tyrosine kinase 1. PlGF=placental growth factor.
