Multivariate models for associations of baseline and previous season predictors of exacerbations. Baseline predictors were allergy (skin tests and total IgE) and age. Previous season predictors were FEV1/FVC ratio, FeNO, exacerbation history and ICS step requirement. Bars length and color indicates the strength of the association between the predictor and seasonal exacerbation as measured by variance explained. The total predictive power of a multivariate model containing all 7 predictors is annotated in the bottom right hand corner. Negative associations are indicated with an asterisk.
