The characteristics of normotensive (NBP), borderline hypertensive (BBP), and hypertensive (HBP) subjects

Parameter	NBP (N=30)	BBP (N=27)	HBP (N=28)	P-value for ANOVA
Male/female	13/17	15/12	17/11	NS
Age (years)	12.0±0.8	11.8±0.8	13.6±0.8	NS
Height (cm)	151±5	151±5	160±4	NS
Serum creatinine (mg/100 ml)	0.66 (0.57-0.70)	0.69 (0.62-0.77)	0.74 (0.68-0.81)	NS
24-h creatinine clearance (ml/min/1.73m²)	135 (127-145)	127 (117-138)	130 (120-141)	NS
UMA (mg/day)	31 (19-51)	22 (14-35)	23 (16-33)	NS
SBP (mm Hg)	109±2	119±2	130±3	<0.0001
DBP (mm Hg)	64±1	68±1	72±2	0.0005

DBP, diastolic blood pressure; NS, not significant; SBP, systolic blood pressure; UMA, urine microalbumin excretion.

Note. SBP: NBP vs BBP (P=0.0122), NBP vs HBP (P<0.0001), BBP vs HBP (P=0.0022); DBP: NBP vs BBP (P=NS), NBP vs HBP (P=0.0003), BBP vs HBP (P=NS). Data presented as mean±s.e. or geometric mean (95% CI).
