Table 2.

Clinical characteristics of subjects with stage 1 primary hypertension from the primary hypertension without renal damage (NRD) group and the primary hypertension with renal damage (RD) group.

Parameters	Subjects with stage 1 primary hypertension
	NRD (n=35)	RD (n=39)
Urinary renalase (μg/ml)	2.17 ± 0.25	1.79 ± 0.24a
UACR (mg/g)	8.17 ± 7.14	64.68 ± 37.48a
SBP (mmHg)	147.71 ± 4.32	151.54 ± 5.24
Pulse pressure (mmHg)	59.51 ± 9.56	62.56 ± 9.53
Sex (M/F)	19/16	22/17
Age (year)	58.14 ± 11.32	56.67 ± 12.95

Non-normally distributed variables are expressed as the median (interquartile range). All of the values are expressed as mean ± standard deviation (SD) or n, %.

NRD: primary hypertension without renal damage; RD: primary hypertension with renal damage; UACR: urinary albumin to creatinine ratio; SBP: systolic blood pressure.

^ap < 0.05, vs. the NRD group.
