Maternal serum placental growth factor concentration in the prediction of growth outcomes and preterm birth in early-onset fetal growth restriction: a retrospective observational study.
OBJECTIVES To evaluate whether low gestation-specific maternal serum placental growth factor (PlGF; ≤5th centile) is associated with adverse outcomes in early-onset fetal growth restriction (FGR), and to compare these associations with those observed for first-trimester pregnancy-associated plasma protein A (PAPP-A), s...
