Multivariate linear regression models of the relationship between the EZSCAN value and arterial stiffness indices.

Model 1 is unadjusted. Model 2 is adjusted for age, sex, smoking, heart rate, body mass index, and waist circumference. Model 3 is adjusted for all covariates from Model 2 plus systolic blood pressure, diastolic blood pressure, triglycerides, HDL cholesterol, and estimated GFR. Model 4 is further adjusted for fasting glucose and postprandial glucose.
*In these models, the variable of systolic blood pressure was not included when the dependent variable was cSBP; the variables of systolic and diastolic blood pressures were replaced by the variable of mean arterial pressure when the dependent variable was baPWV.
