PGF and fetal growth restriction: One study reported that among patients suspected of having SGA fetuses, abnormal maternal plasma concentrations of angiogenic/antiangiogenic factors were 5 to 9 and 8 to 9 times more likely to lead to PE or preterm delivery.[36] Ignacio et al reported the following median values of sFlt-1/PlGF: control group 11.0, fetal growth restriction group 116.8, PE 66.5, and PE combined with fetal growth restriction group 165.4.[37] In our study, we analyzed general population, not in the suspected PE group.
