Improved spirometric detection of small airway narrowing: concavity in the expiratory flow–volume curve in people aged over 40 years

BACKGROUND AND OBJECTIVE: We have explored whether assessing the degree of concavity in the descending limb of the maximum expiratory flow–volume curve enhanced spirometric detection of early small airway disease. METHODS: We used spirometry records from 890 individuals aged ≥40 years (mean 59 years...
