*PA on RHC=pulmonary arterial hypertension diagnosed at right heart catheterisation. Total interstitial disease extent=sum of each of the individual HRCT patterns, except traction bronchiectasis, which was scored based upon severity within each interstitial pattern and summated (see online supplementary appendix).
CTD-FLD, connective tissue disease related fibrotic lung disease; NSIP, non-specific interstitial pneumonia; UIP, usual interstitial pneumonia.
