Nonadjusted means ± standard deviations are shown. The differences between males and females are given, adjusted for age and, when appropriate, height.
Means adjusted for age and height ± standard deviations are shown. The differences between males and females are given, adjusted for age and height.
cResting SBP/DBP is a 5-minute average of SBP/DBP measured while seated after 5 minutes at rest.
CI = confidence interval.
