Table 1 Clinical characteristics of women from three groups in the present study

	Non-pregnant	Normal pregnant	Severe preeclampsia
	(n = 60)	(n = 60)	(n = 60)
Age (years)	30.4 ± 3.9	29.0 ± 0.6	29.5 ± 4.7
Gestational age (weeks)	NA	38.6 ± 0.3	33.1 ± 4.6*
Systolic blood pressure (mmHg)	118.7 ± 6.8	115.5 ± 1.6	168.0 ± 15.7*
Diastolic blood pressure (mmHg)	74.7 ± 6.3	73.9 ± 1.4	109.6 ± 12.4*

Data are mean ± SD. Student’s unpaired two-tailed t-test was used to compare the non-pregnant to the normal pregnant group and the normal pregnant group to the severe preeclampsia group. Significant differences are indicated by * (p < 0.001).
Nd: not determined; NA: not applicable.
†: Urine protein of normal pregnant and non-pregnant women was within normal ranges and not routinely recorded.
