In the table: age-adjusted mean (proportion) for continuous and dichotomous variables respectively, estimated at the sample mean age. Results for men and women combined are also adjusted for gender, and estimated at the observed prevalence of men in the sample. For continuous variables, the estimated mean is reported ± standard error. Mean ABI: average of Left and Right; #: Abnormal cfPWV: cfPWV≥12 m/s; ° PAD: either left or right side ABI ≤0.9; *Testing the null hypothesis of no association between occupational classes and each feature, from linear (logistic) regression model with age as covariate for continuous and dichotomous variables respectively. The p-value is relative to the F Test (with 3df) or to Chi-Square Test (with 3df) for continuous and dichotomous variables, respectively.
