Association between immunosuppressant (IS) exposure (mycophenolate or azathioprine) compared with no exposure and 2-year transplant-free survival in fibrotic hypersensitivity pneumonitis (fHP) and unclassifiable interstitial lung disease (uILD) patients stratified by age-adjusted leukocyte telomere length (LTL) <10th and ≥10th percentile of normal. Weighted Cox proportional hazards regression model with robust variance estimation and adjustment for radiographic honeycombing and centre.
