Abstract

Background Bronchiectasis is a respiratory disease structurally characterised by irreversible airway dilatation. Functional impairments are also implicated in bronchiectasis, but the detailed changes in pulmonary function and the impact of clinical factors are yet to be examined. We analysed pulmonary function in patients with bronchiectasis based on their clinical features. Methods Two study cohorts—a multicentre bronchiectasis registry and health check-up examinees—were analysed. Airflow limitation was defined as forced expiratory volume in 1 s (FEV 1 )/forced vital capacity (FVC)
