Results are expressed as mean (SD) or n(%). ILD = interstitial lung disease, IPF = interstitial pulmonary fibrosis, FVC = forced vital capacity, TLCO = diffusing capacity for carbon monoxide, RVSP = right ventricular systolic pressure, VO2peak = peak oxygen uptake, 6MWD = 6-minute walk distance. *p<0.05 vs IPF subgroup.
