Abbreviations: afPWV, aortic-femoral pulse wave velocity; DBP, diastolic blood pressure; NS, not significant; SBP, systolic blood pressure.
a Covariates included age, sex, body mass index, heart rate, smoking, diabetes, and duration of follow-up.
b ρ1 represents the path from afPWV, C1R, or C2R to BP.
c ρ2 represents the path from BP to afPWV, C1R, or C2R.
d P value for difference between ρ1 and ρ2 within racial/ethnic groups.
e For ρ1 and ρ2 being different from 0, P < 0.01.
f P > 0.05.
g For ρ1 and ρ2 being different from 0, P < 0.05.
h C1R, large-artery (capacitive) compliance × systemic vascular resistance; C2R, small-artery (oscillatory) compliance × systemic vascular resistance.
