Dx, diagnosis; COPD, chronic obstructive pulmonary disease; PAH, pulmonary arterial hypertension; CF, cystic fibrosis; DM-ILD, dermatomyositis-associated interstitial lung disease; HP, hypersensitivity pneumonitis; MCTD, mixed connective tissue disease; FVC, forced vital capacity; FEV1, forced expiratory volume in one second. The unit for FVC and FEV1 is litter. For each of the figures in the parenthesis of FVC, the column is the percentage of the predicted FVC, value. Each of the figures in the parenthesis of the FEV1 column is the percentage of the predicted FEV1 value.
