The median umbilical cord plasma concentrations of normal neonates (7.2 ng/ml, interquartile range [IQR] 5.8–8.0), SGA newborns (7.1 ng/ml, IQR: 5.7–9.5) and infants of patients with preeclampsia (7.4 ng/ml, IQR: 5.6–8.2) did not differ significantly (p=0.8, Kruskal-Wallis). Similarly, the median umbilical cord plasma visfatin concentrations did not differ significantly between neonates of patients with preeclampsia and those delivered preterm without preeclampsia matched for gestational age (7.4 ng/ml, IQR: 5.6–8.2 vs. 7.1 ng/ml, IQR: 6.4–7.7).
