Line graph showing TFS for patients with IPF ILD and non-IPF ILD stratified by the presence of FPF. TFS was significantly worse for patients with familial IPF compared with those with sporadic IPF (P = .01, log-rank test) and familial non-IPF ILD compared with their counterparts with sporadic disease (P = .002, log-rank test). No difference was found in survival between patients with familial non-IPF ILD and sporadic IPF ILD (P = .42, log-rank test). FPF = familial pulmonary fibrosis; ILD = interstitial lung disease; IPF = idiopathic pulmonary fibrosis; TFS = transplant-free survival.
