  2. Adjusted for age, sex, centre, BMI, self-reported hypertension, and smoking status (ever, never).
  3. High confidence exposures include only those exposures assessed with a confidence of probable (40–90%) or definite (>90%).
  4. Occupational exposures to ceramic fibres (cases N=1; controls N=1) and charcoal dust (cases N=1; controls N=1) are not shown due to small number of exposed.
