  1. aOR, odds ratio; CI, confidence interval. All models were stratified by age.
  2. bSmoking variables: quitting smoking, smoking status in pack-years (0, <20, 20–40, >40).
  3. cAlcohol variables: alcohol consumption in grams ethanol/day (<25, 25–75, >75).
  4. dOJI, Overall Job Demand; PJI, Physical Job Demand; PSI, Psycho-social job demand; CAI, Carcinogenic Agent Exposure. The average of all indices per person for all lifetime performed jobs; per 2 units increase of the respective indices.
