  1. BMI body mass index, FEV1 forced expiratory volume in 1. second, FVC forced vital capacity, B-eosinophils blood-eosinophils, MRC medical research council
  2. P-values less than 0.05 are considered statistically significant (displayed in italic text) and calculated for the difference between the subgroup < 2 and ≥ 2 exacerbations per year
