Figure 1. Mean Cumulative Number of Severe Asthma Exacerbations per Participant over Time, with Adjusted Hazard Ratio.

Figure 1.

Shown are the mean cumulative numbers of severe asthma exacerbations per participant over time. Participants in the intervention group received patient-activated, reliever-triggered inhaled glucocorticoid in addition to usual care. Differences in treatment-group hazards were compared with the use of the Andersen–Gill model with adjustment for prespecified covariates.
