Background: Small airway obstruction is a common feature of obstructive lung diseases. Research is scarce on small airway obstruction, its global prevalence, and risk factors. We aimed to estimate the prevalence of small airway obstruction, examine the associated risk factors, and compare the findings for two different spirometry parameters. Methods: The Burden of Obstructive Lung Disease study is a multination...
