Evaluation of rheumatoid arthritis and connective tissue disease-related interstitial lung disease with pulmonary physiologic test, HRCT, and patient-based measures of dyspnea and functional disability.

• HRQoL may be affected differently among specific subtypes of ILD. • PROs can be used to evaluate dyspnea and function of patients with RA- or CTD-related ILD but are not distinguished from patients with cough and/or shortness of breath due to non-ILD causes in RA/CTD.
