Fig 1. Kaplan−Meier survival curves for candidates with interstitial lung disease (ILD) grouped by diagnosis; idiopathic pulmonary fibrosis (n = 33), unclassifiable ILD (n = 15), and other ILDs (n = 29).

Other ILDs: idiopathic nonspecific interstitial pneumonia (n = 4), pleuroparenchymal fibroelastosis (n = 1), connective tissue disease-associated ILD (n = 17), and chronic hypersensitivity pneumonitis (n = 7).
