Figure 2: Asthma-related measures for the ICS/LABA cohorts during the baseline year and the year after step-down in ICS dose to a once-daily regimen (A) or a twice-daily regimen (B). In the QD cohort, the number of exacerbations and asthma and primary care consultations decreased significantly between baseline and post step-down (p ≤ 0.04). In the BD cohort, all measures improved significantly between baseline and post step-down (p<0.001).
