Transplant-free survival among NAC exposed and non-exposed individuals with UIP stratified by ANA antibody status. Among ANA seropositive individuals (a), NAC exposed individuals demonstrated improved survival compared to NAC non-exposed individuals (plogrank = 0.02; HR 0.55, 95% CI 0.32–0.92). Among ANA seronegative individuals (b), survival did not differ between NAC exposed and non-exposed individuals (plogrank p = 0.92; HR 1.03, 95% CI 0.56–1.87)
