Prediction of preterm birth in growth‐restricted and appropriate‐for‐gestational‐age infants using maternal PlGF and the sFlt‐1/PlGF ratio—A prospective study

To assess the utility of placental growth factor (PlGF) levels and the soluble fms-like tyrosine kinase-1/placental growth factor (sFlt-1/PlGF) ratio to predict preterm birth (PTB) for infants with fetal growth restriction (FGR) and those appropriate for gestational age (AGA).
