From: Impact of baseline symptoms and health status on COPD exacerbations in the FLAME study
Annualised rate of COPD exacerbations by baseline dyspnoea level measured via eDiary. n, number of patients assessed in this analysis. Dyspnoea was measured via eDiary based on median split of daily highest dyspnoea scores averaged over the run-in period. CI, confidence interval; COPD, chronic obstructive pulmonary disease; eDiary, electronic diary; IND/GLY, indacaterol/glycopyrronium 110/50 μg once daily; SFC, salmeterol/fluticasone 50/500 μg twice daily
