NWO normal weight obesity, NWL normal weight lean, PWV pulse wave velocity, CACS coronary artery calcium score. Analysis of covariance (ANCOVA) using age, sex, and smoking status as covariates was used to evaluate the difference of continuous variables and dichotomous variables between NWL and NWO subjects. Continuous variables are presented as mean ± standard deviation. Dichotomous variables are presented as the number of subjects with the percentage of subjects in the parenthesis
