PWV, pulse-wave velocity; CACS, coronary artery calcium score. A one-way analysis of variance was used to evaluate the difference of PWV or number of coronary segments involved between CLO negative and positive subjects with age adjustment. The generalized estimating equation was used to evaluate the difference of dichotomous variables between the two groups with age adjustment. Continuous variables are presented as mean±standard error. Dichotomous variables are presented as the number of subjects with the percentage of subjects in the parenthesis. P < .05 was regarded as statistically significant.
