  • *: the following post hoc comparisons were significant at the p=0.05 level

  • all other comparisons were nonsignificant: usual interstitial pneumonia (UIP) versus fibrotic nonspecific interstitial pneumonia (NSIP), cellular NSIP and respiratory bronchiolitis interstitial lung disease/desquamative interstitial pneumonia (RBILD/DIP) (chest radiographic (CXR) score)

  • RBILD/DIP versus UIP and fibrotic NSIP (exercise component of the composite physiological score 7 (exercise component). See Clinical, radiological and physiological scoring section for details. UIP versus RBILD/DIP (CRP total score)

  • ANOVA: analysis of variance

  • LOD: level of dyspnea 7

  • PHYSIO: composite physiological score (see clinical, radiological and physiological scoring section for details).
