Completion and compliance
Completion and compliance rates were summarized for each HRQoL instrument and outcome. An instrument was considered complete if at least one valid scale score could be computed from the available response data. The rate was computed as a percentage of patients in the full analysis set. The compliance rate was the percentage of patients who had completed the instrument among all patients who were expected to complete the instrument at a certain time point (i.e., the number of patients with a valid baseline score who were enrolled in the study and taking the study treatment at that time point).
