Prevalence of respiratory symptoms (inclusive of those with a history of persistent cough or dyspnea during the 12 months preceding the lung health check [LHC]) in participants with a FEV₁:FVC <70% on the pre–low-dose computed tomography (LDCT), prebronchodilator spirometry, and with or without emphysema detected at LDCT. *Termed “chronic obstructive pulmonary disease” (COPD) solely on the basis of LHC spirometry. FEV₁ = forced expiratory volume in 1 second; FVC = forced vital capacity.
