Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: This study was designed to determine maternal plasma/urine/hair magnesium and vanadium concentrations in women with LOPE (n=70) compared to those of normotensive pregnant women (n=70) and to those of normotensive-healthy non-pregnant women (n=70). These metals concentrations will be measured using inductively coupled plasma-mass spectrometry were compared.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Preeclampsia
The diagnosis of LOPE, as will be defined by the Committee on Terminology of the American College of Obstetricians and Gynecologists (ACOG), will be established based on the presence of proteinuria and a blood pressure level of ≥140/90 mmHg that occurs after 34 weeks of gestation in a previously normotensive woman. The diastolic and/or systolic blood pressure ≥ 160/110 mm Hg, it will be accepted as mild; and in case these values exceeded this level, it will be accepted as severe.

control non-pregnant group
A volunteer group of healthy women who visited the gynaecology clinic for routine examinations and women who were admitted for pre-pregnancy tests were invited randomly to this research as a control group.
