Parameter Estimates From the Final Model Where Disease Was Treated as a Single Factor With Four Groups

Parameter	Regression Coefficient	P Value
Hypertensive + obese	0.77 (0.42–1.12)	<.001
Obese	0.75 (0.39–1.11)	<.001
Hypertensive	0.47 (0.05–0.89)	.03
Age, y	0.10 (0.04–0.16)	.002

Regression coefficients (95% confidence intervals) correspond to the covariate‐adjusted mean difference relative to the control group, and the coefficient for age corresponds to the slope. Each condition adds to the baseline pulse wave velocity (control) by the amount of the regression coefficient. Race, sex, and interaction (disease × age) were not significant and were not retained in the final model.
