  1. a Categories for occupational social prestige scores according to tertiles among control subjects: Low (L) = 13- ≤ 35, Medium (M) = >35- ≤ 45, and High (H) = >45–78 points
  2. b Odds ratios for model 1 are adjusted for study center and log(age)
  3. c Odds ratios for model 2 are additionally adjusted for smoking status with time since quitting (2–7, 8–15, 16–25 or ≥26 years before interview/diagnosis, other types of tobacco only, non-smokers), and log(pack-years + 1)
  4. d Odds ratios for model 3 are additionally adjusted for ever working in “List A” occupation
  5. e Odds ratios for model 4 are additionally adjusted for highest education
