The Association of Lung Clearance Index with COPD and FEV1 Reduction in 'Men Born in 1914'

This population-based study examines whether LCI predicts pulmonary obstruction and incidence of chronic obstructive pulmonary disease (COPD) events over a long-term follow-up. 
The conclusion is: Reduction of FEV1 between 55 and 68 years of age and incidence of pulmonary obstruction was highest in those with high LCI. High LCI is associated with future development of pulmonary obstruction and incidence of COPD hospitalisations in men from the general population.
