From: Impact of baseline symptoms and health status on COPD exacerbations in the FLAME study
Annualised rate of COPD exacerbations by baseline bronchitis status measured via eDiary. n, number of patients assessed in this analysis. Bronchitis was evaluated based on patients’ response to a specific question in the eDiary. Bronchitis and non-bronchitis patients were defined as those with daily highest sputum volume score of ≥1 (bronchitis) or < 1 (non-bronchitis) for ≥50% of the time during 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
