SBP, systolic blood pressure; DBP, diastolic blood pressure; FG, fasting glucose; TC, total cholesterol; LDL-C, low density lipoprotein cholesterol.
p value is for ANOVA between 4 groups.
^
p<0.05,
^^
p<0.01, significantly different from low-risk group;
#
p<0.05,
##
p<0.01, significantly different from moderate-risk group;
∆∆
p<0.01, significantly different from high-risk group;
†
p<0.05, significantly different from <80 yr.
On BP medication is for hypertensive individuals. Attain SBP goal is for subjects on medication.
