Definition of abbreviation: CI = confidence interval.

Model 1 is unadjusted. Model 2 is adjusted for age and sex. Model 3 includes model 2 parameters plus baseline blood eosinophils and asthma exacerbations. Model 4 includes model 3 parameters plus baseline oral corticosteroid use. Model 5 includes model 4 parameters plus baseline body mass index.
