  1. CI = confidence interval; ICS = inhaled corticosteroid; OR = odds ratio
  2. *Adjusted for baseline confounding factors, including short-acting β-agonist use, asthma consultation rate, socioeconomic status, and prescribed ICS dose at the index date (time of ICS device switch).
  3. †Successful treatment vs. partially successful/unsuccessful treatment.
  4. ‡Unsuccessful treatment vs. successful/partially successful treatment.
