摘要

Results suggest that the CASA-Q is appropriately responsive to changes in cough and sputum symptoms and clinical impact in trials of COPD. The mapping of qualitative findings from online SML and OBB studies to CASA-Q domains and items confirm the content validity of the instrument. These results suggest the CASA-Q can be a valuable tool for evaluating treatment effect in COPD trials.
