  1. AWT, airway wall thickness; FEV1, forced expiratory volume in 1-second; FVC, forced vital capacity; MMRC, Modified Medical Research Council Dyspnea Scale; Pi10, square root of the wall area for a theoretical airway with an internal perimeter of 10Ā mm; SGRQ, Saint Georgeā€™s Respiratory Questionnaire
  2. Models evaluating mortality and 5-year change in mMRC as binary and survival outcomes were logistic and Cox proportional hazards models, respectively. All other regression models used linear regression. All models were adjusted for genetic ancestry, sex, age, and packs smoking at baseline
  3. Models for all-cause mortality were additionally adjusted for clinical site at baseline
