Figure 3. Time commitment to CF treatments versus airway clearance methods and gender, N = 54 responses. Data points indicate total time estimated for treatments among respondents who used the indicated airway clearance methods at bottom. Some respondents reported current use of multiple methods. Vest users reported more time commitment to daily treatments. In a generalized linear model of time commitment by age, gender, CFTR modulator use, and airway clearance method, vest usage was independently associated with the most reported time for treatments (P < 0.0001).
