- CPD cardiopulmonary disease, HR hazard ratio, LC lung cancer, WS woodsmoke
- aPerson-year was calculated as age at last alive LC-free contact or age at LC diagnosis for lung cancer incidence analyses or age at last alive contact or age at death for mortality analyses. Age at death was missing for one subject with ever WS exposure
- bBaseline values of age, smoking status, and packyears, sex, and ethnicity were included in Cox proportional hazards model for covariate adjustment for LC incidence. Education and income were included for additional covariate adjustment for mortality
- cDeaths due to non-CPD causes were censored at the date of death
- dDeaths due to non-cancer causes were censored at the date of death
