Low-intensity treatment indicates low ICS (fluticasone [44 µg per puff] 2 puffs twice per day) and albuterol as needed; high-intensity treatment, high ICS (fluticasone [220 µg per puff] 2 puffs twice per day), LABA, LTM, and albuterol as needed. Analyses compared vignettes 2, 3, 4, 5, and 6 with vignette 1 (stepping-up baseline), and vignettes 8, 9, 10, and 11 were compared with vignette 7 (stepping-down baseline).
