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.
