Role of lung function, chronic obstructive pulmonary disease on hearing impairment: Evidence for causal effects and clinical implications

This cross-sectional study investigated the associations between lung function, COPD, and hearing impairment, based on data from 109,668 adults enrolled in the UK Biobank. Lung function parameters included FEV1, FVC, and the FEV1/FVC ratio, which were obtained using a Vitalograph Pneumotrac spirometer.
