(A) Cystic Fibrosis Questionnaire–Revised, Respiratory Domain (CFQ-R RD) with participants grouped into categories at each visit. The top category (100, light green) represents the maximum achievable score, which a substantial number of participants obtained 6 months after elaxaftor/tezacaftor/ivacaftor initiation. Labels are omitted for categories with too few participants. (B) The same plot split into categories based on baseline percent predicted FEV₁ (ppFEV₁). The trend toward the maximum score was observed at each level of baseline lung function, with higher proportions in the high baseline lung function cohort reporting maximal CFQ-R RD at 6 months.
