Prevalence of (A) reported respiratory symptoms within 12 months preceding the lung health check, (B) reported inhaler use, and (C) reported comorbidities, by chronic obstructive pulmonary disease (COPD) group. *P ≤ 0.05 and **P ≤ 0.001. COPD groups: “no COPD” (FEV₁:FVC ≥70%); “undiagnosed COPD” (FEV₁:FVC <70% and no reported history of COPD); and “known COPD” (FEV₁:FVC <70% and a reported history of COPD). FEV₁ = forced expiratory volume in 1 second; FVC = forced vital capacity; ICS = inhaled corticosteroid; LABA = long-acting β-agonist; LAMA = long-acting antimuscarinic agent; LRTI = lower respiratory tract infection; SABA = short-acting β-agonist.
