Productive cough associated with patient-reported outcomes and computed tomography analysis results in idiopathic pulmonary fibrosis: a single centre cross-sectional study

Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic pulmonary disease that causes mortality in most patients [1, 2]. Cough and dyspnoea are the most common symptoms of IPF. However, the effect of cough on the pathophysiology of IPF has not been extensively investigated. Although the cough of patients with IPF is often described as dry [3], mucus hypersecretion and ciliary impairment in the conducting airway are reported to be common among these patients [4].
