  1. The Cox regression model = treatment group + severity of asthma (GINA treatment steps 3, 4 and 5) + region as fixed class effects, stratified by randomization stratum (fevipiprant 150 mg once daily in LUSTER-1/LUSTER-2, fevipiprant 450 mg once daily in LUSTER-1/LUSTER-2, Placebo in LUSTER-1/LUSTER-2, fevipiprant150 mg once daily in ZEAL-1/ZEAL-2, Placebo in ZEAL-1/ZEAL-2, New patients). Patients without the event of interest were censored at the minimum out of the dates of last medication intake + 30 days, final visit date, and date of death
  2. A hazard ratio < 1 favors the treatment group in the numerator of the ratio
  3. AE adverse event; n number of patients with at least one event; m total number of patients included in the analysis; TEAE treatment emergent AE
