Abbreviations: COPD, chronic obstructive pulmonary disease; CTD-ILD, connective tissue disease related ILD; DLCO, diffusing capacity of the lungs for carbon monoxide; FVC, forced vital capacity; ILD, interstitial lung disease; IPF, idiopathic pulmonary fibrosis; 6MWD, 6-minute walk distance; 6MWT, 6-minute walk test; MDC, multidisciplinary collaborative care; MRC, medical research council; NRS, numerical rating scale; NSIP, nonspecific interstitial pneumonia; OSA, obstructive sleep apnea; SD, standard deviation; SpO2, peripheral capillary oxygen saturation.
aBaseline FVC, DLCO, 6MWD, 6MWT Resting and Nadir SpO2 were defined as results from the time of or within 3 months of first MDC visit. Not all patients had test results within this period. 66 patients had FVC results, 49 patients had DLCO results, 48 had 6MWD and nadir SpO2 results, 47 had resting SpO2 results.
bBaseline NRS is defined as the first available NRS score.
