  1. Values are the mean ± SEM. PE, preeclampsia; BMI, body mass index; GAD, gestational age at delivery; MPE, mild preeclampsia; SPE, severe preeclampsia; SBP, systolic blood pressure; DBP, diastolic blood pressure; ND: not determined but negative using dipstick test. P values were calculated between the control and preeclampsia group. NS, non significant. Control vs. MPE and SPE; MPE vs. SPE. ♦♦ MPE vs. SPE
