  2. aβ-Coefficients (p value) modeled as univariate regression analyses. 6MWT and muscle strength modeled as percent predicted. β-Coefficients represent the percent change in the physical functioning variable per unit change in exposure variable
  3. bEach domain of the EuroQol-5D questionnaire modeled as 0 “no problems” and 1 “any problems”
  4. cVisual analog scale of the EQ-5D scores ranges from 0 to 10 based on patients perspective of current overall health
  5. dThe physical function domain is standardized to a 0–100 scale, and higher scores indicate better health-related quality of life
  6. ePhysical and mental composite scores of the short-form 36 survey, standardized to Canadian norms. Scores can range from 0 to 100 and are standardized to 50, which represents the average Canadian’s health-related quality of life
  7. fHospital Anxiety and Depression Scale (HADS), scores range from 0 to 21, significant symptoms of anxiety/depression defined as scores ≥8
