Data are presented as mean ± standard deviations or n (%). Spearman’s rho (r), standardised ß values, odds ratios (OR) and P values are reported for the association with aortic PWV, in univariate analysis or multivariate analysis with the covariates age, gender, MAP, heart rate, BMI, smoking, DM duration and hypertension. *P value < 0.05
