Table 1

Diagnostic criteria for preeclampsia [8].

Blood pressure	Systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg that are noted twice within 6 hours after 20 weeks of gestation in women with normal blood pressure before conception or in women with previous chronic hypertensive disorders
And coexistence of one or more of the following new-onset conditions
Proteinuria	Spot urine protein/creatinine >30 mg/mmol (0.3 mg/mg) or >300 mg/day or at least 1 g/L (“2+”) on dipstick testing
Other maternal organ dysfunctions	(1) Renal insufficiency (creatinine >90 μmol/L; 1.02 mg/dL)
	(2) Liver involvement (doubling of serum transaminases and/or severe right upper quadrant pain)
	(3) Neurological complications (eclampsia, altered mental status, blindness, stroke, or more commonly hyperreflexia when accompanied by clonus and severe headaches when accompanied by hyperreflexia and persistent visual scotomata)
	(4) Hematological complications (platelet count <150,000/dL, DIC, and hemolysis)
Uteroplacental dysfunction	Fetal growth restriction

DIC, disseminated intravascular coagulation.
