Comparison of poor asthma control factors in controller naïve with on controller subset. Controller therapy status significantly impacts relationship between night symptoms, beta₂-agonist use, and school days missed on likelihood of positive BDR at one or more threshold levels, unadjusted for other factors (p<.05). Non-significant subset differences were found for the following factors: atopy, family history, day symptoms, exercise limitations, steroid bursts, exacerbations, and emergency department visits/hospitalizations. View non-significance with caution due to limited number of patients on controller therapy at baseline.
