Results presented as mean±SD for continuous variables and n (%) for categorical variables.

*Data on diabetes, hypertension, hyperlipidaemia, obesity, chronic renal insufficiency and obstructive pulmonary disease were available for 322 white collar workers and 234 blue collar workers.

†Data on CAD were available for 209 white collar workers and 157 blue collar workers.

CAD, coronary artery disease; SCD, sudden cardiac death.
