A significant negative correlation of IUGR (p = 0.0030; p < 0.0001), placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p = 0.0183 and p < 0.000), and postpartum haemorrhage (PPH) (p = 0.0420; p = 0.0044) were associated with both PLGF and T-AOC whilst a significant positive correlation of IUGR, placental abruptio (p < 0.0001; p < 0.0001), IUFD (p < 0.0001; p < 0.0001), stillbirth (p < 0.0001; p < 0.0001), and PPH (p = 0.0043; p = 0.0039) were observed with both sFlt-1 and 8-epi-PGF2α in PE. Here, PGF is linked to pulmonary arterial hypertension.
