Figures & data

Table 1 Characteristics Of The COPD Patients Divided In The Subgroups With Respect To Benefit And Appropriateness Of ICS Therapy In COPD

Figure 1 (A) COPD treatment as percentages of patients in the different COPD treatment groups for all study patients (n = 561). (B) Percentages of patients by severity of airflow limitation and by COPD treatment for all study patients (n = 561).

Abbreviations: FEV1, forced expiratory volume in 1 second; ICS, inhaled corticosteroid; LABA, long-acting beta-2-agonist; LAMA, long-acting muscarinic antagonist.

Figure 2 Flow chart of categorizing the COPD patients (n = 561) into subgroups based on comorbidity of asthma, history of exacerbations, B-Eos count and treatment of ICS.

Abbreviations: Frequent exa, frequent exacerbations, ≥2 exacerbations treated in primary care or at emergency room and/or ≥1 hospital admissions during the previous year due to worsening in COPD; B-Eos, blood eosinophil count as cells/µL; ICS, inhaled corticosteroid.
