Notes: aThe China symptomatic population was defined as patients in the China ITT population with a CAT score ≥15 at screening. bTDI focal score over 24 weeks was based on assessments at Weeks 4, 8, 12, 16, 20, and 24. All p-values <0.05 should only be interpreted in terms of nominal significance as the analyses in the Chinese subgroup were considered exploratory.
