FIGURE 2.

Inclusion criteria for fibrosing interstitial lung disease (ILD). Evidence of fibrosing ILD will be confirmed by central review (lung biopsy and high-resolution computed tomography (HRCT)). NSIP: non-specific interstitial pneumonia; UIP: usual interstitial pneumonia. ^#: Coexisting cystic abnormalities or ground-glass opacity are acceptable; however, coexisting multifocal non-fibrotic, non-dependent consolidations (e.g. organising pneumonia, infection) will not be permitted. ^¶: With or without ground-glass opacification.
