Results: At >37 weeks of gestation, the median (IQR) PlGF level was significantly lower in the IUGR group (35 (13, 51) pg/mL) than in the normal pregnancy group (108 (65, 220) pg/mL; p < 0.001), but the difference was not significant at <37 weeks. This evidence concerns the gene PGF and fetal growth restriction.
