*All RRs, except for the unadjusted case-cross-over, are adjusted for the following variables estimated in the 180 days prior to the start of the time window: number of asthma-related hospital admissions, outpatient services use, medication dispensations, number of dispensations of short-acting beta-agonists, inhaled corticosteroids, and combined inhaled corticosteroids and long-acting beta-agonists, as well as total number of hospital admissions, outpatient services use, medication dispensations, and the Charlson co-morbidity index.
