All serum analysis is in terms of pg/mL and each analyzed factor is displayed with mean and standard deviation in light blue bars for the two separate populations, severe preeclampsia cases and normotensive controls. p-Values performed for each factor are (A) p < 0.001 (B) p = 0.002, (C) p = 0.249, (D) p = 0.006, respectively. NPP, normotensive postpartum; PlGF, placental growth factor; sEng, soluble endoglin; sFlt-1, soluble fms-like tyrosine kinase-1; sPE, severe preeclampsia.
