Definition of abbreviations: FEV1 = forced expiratory volume in 1 second; FVC = forced vital capacity; IPF = idiopathic pulmonary fibrosis; mMRC = modified Medical Research Council.
Data are presented as the mean ± SD, unless stated otherwise. Demographic information for the lung-cancer control group was unavailable. Lung biopsy specimens from the cohort described in this table form the tissue microarray assembled for Figure 1.
*
Dyspnea was evaluated using the mMRC scale. Scores range from 0 to 4, with higher scores indicating worse dyspnea.
