aBaseline model is stratified by occupational classes
bAdjusted model 1 is adjusted for the confounding variables age (continuous variable), gender (male/female), and education (continuous variable)
cAdjusted model 2 has additional adjustment for the confounding variables smoking (current, former, never), physical activity (continuous variable), BMI (continuous variable) and CVD (yes/no)
