  1. Abbreviation: SC Self-Care, MO Mobility, Trans Transfer, FIM Functional Independence Measure
  2. aThe primary type of non-response option was determined based on the highest frequency of non-response type for Section GG. If patient had same frequency of two more types, this case was considering as ‘Tie’ category
  3. bChange score of GG was calculated as discharge score minuses admission scores (e.g. GGSC Change = Discharge GGSC – Amission GGSC). Thus, we did not have information on patients with non-response data
  4. cThe GG mobility score at admission and discharge is created using 15 GG items, excluding two wheelchair items
