Real-World Study Limitations: Prespecified interim analysis of a single-arm, prospective, observational cohort study; may not reflect results from final dataset.
Real-world studies are designed to evaluate associations among variables and not to definitively establish causality. Limitations important when interpreting results: no comparator arm; differences in patient populations and data collection vs randomized controlled trials.
*Baseline maintenance OCS dose (as prednisone equivalent mg/day) as 28-day period at initiation or within prior 6 months (n=159).
†OCS dose assessment based upon data captured from medical records or patient recall, without documentation of asthma control.
