Multivariable model adjusted for age, sex, cohort, mean arterial pressure, heart rate, body-mass index, total/high density lipoprotein cholesterol ratio, triglycerides, glucose, diabetes, current smoking, hypertension treatment, lowering lipid treatment, walk test (before), prevalent CVD.
LSM = least squares mean, SE = standard error.
PWV = pulse wave velocity.
