Comparison of breath profiles between patients with ILD and other respiratory diseases. A Scatterplot of patients with ILD (n = 161) versus other respiratory diagnoses (i.e. asthma, COPD, and lung cancer; n = 161). B Scatterplot of patients with ILD (n = 55) versus asthma (n = 65) versus COPD (n = 50) versus lung cancer (n = 46). C Scatterplot of patients with IPF (n = 61) versus COPD (n = 50) versus lung cancer (n = 46). Each dot represents one patient. Component 1 and 2 are principal components resulting from partial least squares discriminant analysis. COPD: chronic obstructive pulmonary disease; ILD: interstitial lung disease; IPF: idiopathic pulmonary fibrosis
