PGF and newborn respiratory distress syndrome: have already shown that infants with a high maternal sFlt-1/PlGF ratio above 85 had a lower birth weight (1142 ± 472 g vs. 2311 ± 236 g, p<0.001) and a higher risk for prematurity, BPD and respiratory distress syndrome (RDS) compared to the low ratio group (13).
