    Abstract: Background: Pre-eclampsia is a hypertensive disorder in pregnancy, that has adverse maternal and perinatal outcomes. Abnormal serum lipid levels have been implicated in the pathogenesis of pre-eclampsia, this can give rise to increased oxidative stress and then subsequently, endothelial dysfunction. Methods: This study was a comparative cross-sect... Show More
