Air pollution associated with cardiopulmonary disease and mortality among participants with preserved ratio impaired spirometry

This study investigated the relationship between air pollutants, cardiopulmonary disease, and mortality in 36,149 participants with PRISm enrolled in the UK Biobank. Lung function data (FEV1, FVC, FEV1/FVC ratio) were based on pre-bronchodilator spirometric testing, which was undertaken using the Vitalograph Pneumotrac spirometer.
