*COPD defined as forced expiratory volume in 1 s (FEV1)/forced vital capacity (FVC) <0.70 and graded as follows; GOLD 1=per cent predicted FEV1 (ppFEV1) ≥80; GOLD 2=50≤ ppFEV1 <80; GOLD 3=30≤ ppFEV1 <50; GOLD 4=ppFEV1 <30.
†ABCD groups defined as follows; A=dyspnoea ≤grade 1, GOLD 1 or 2, and ≤1 exacerbation last 12 months; B=dyspnoea ≥grade 2, GOLD 1 or 2, and ≤1 exacerbation last 12 months; C=dyspnoea ≤grade 1, and GOLD 3 or 4 or ≥2 exacerbations last 12 months; D=dyspnoea ≥grade 2, and GOLD 3 or 4 or ≥2 exacerbations last 12 months.
