Linear mixed models.

(a) Model A: estimated coefficients, 95% CI, and value after using linear mixed model on PWV~Age+BMI+MAP+HR+SV

Variables	Estimated coefficients	95% CI	value
Age	0.007	−0.006, 0.021	0.30
BMI	−0.03	−0.06, −0.0006	0.06
MAP	0.026	0.022, 0.028	<0.001
HR	0.002	−0.003, 0.008	0.47
SV	−0.01	−0.13, −0.007	<0.001

BMI: body mass index; CI: confidence interval; HR: heart rate; MAP: mean arterial pressure; SV: stroke volume.

(b) Model B: estimated coefficients, 95% CI, and value after using linear mixed model on PWV~Age+BMI+MAP+HR+SVR

Variables	Estimated coefficients	95% CI	value
Age	0.007	−0.007, 0.022	0.35
BMI	−0.035	−0.07, −0.003	0.04
MAP	0.014	0.01, 0.018	<0.001
HR	0.017	0.01, 0.02	<0.001
SVR	0.0007	0.0004, 0.0009	<0.001

BMI: body mass index; CI: confidence interval; HR: heart rate; MAP: mean arterial pressure; SVR: systemic vascular resistance.

(c) Model C: estimated coefficients, 95% CI, and value after using linear mixed model on PWV~Age+BMI+MAP+CO

Variables	Estimated coefficients	95% CI	value
Age	0.008	−0.007, 0.023	0.32
BMI	−0.023	−0.056, 0.009	0.19
MAP	0.023	0.01, 0.029	<0.001
CO	−0.046	−0.13, 0.04	0.31

BMI: body mass index; CI: confidence interval; CO: cardiac output; MAP: mean arterial pressure; SVR: systemic vascular resistance.
