a Variables with p < 0.05 in the univariate analysis were selected as independent variables in the multivariate analysis. Serum triglyceride levels were excluded in the multivariate analysis because of the collinearity between total cholesterol and triglyceride.
b The reasons for the inverse relationship between higher brachial-ankle pulse velocity and higher job strain (i.e., higher job demands and lower job control) are discussed in the text.
c NS, not significant (p > 0.05).
*p < 0.05, **p < 0.01, ***p < 0.001
