  1. aThe logistic asthma exacerbation outcome was defined as 1 = any exacerbations/year, 0 = no exacerbations. Sex 1 = male, 0 = female, age, age2 and poverty index were modeled as continuous variables
  2. bThe Poisson asthma exacerbation outcome was defined as number of asthma exacerbations per year. Sex 1 = male, 0 = female, age, age2 and poverty index were modeled as continuous variables
