Association between FEV/FVC levels and all-cause mortality in the general population.

Background: The ratio of the forced expiratory volume in 1 s (FEV) to the forced vital capacity (FVC) is an essential tool for the diagnosis of chronic obstructive pulmonary disease (COPD). However, the relationship between levels of FEV/FVC and mortality in the general population remains unclear, particularly its non-linear relationship. Therefore, we aimed to explore the association between the FEV/FVC and all-cause mortality in the general population.

Association of Forced Expiratory Volume in 0.5s With All-Cause Mortality Risk in Adults.

Introduction: Previous studies have proposed forced expiratory volume in 0.5s (FEV) to determine health outcomes in infants and young children, but few studies exist in adults. This study aims to investigate the associations between FEV and all-cause mortality in adults.
