  1. Results are presented as n (%) unless indicated otherwise. Percentages may not add up to 100 due to rounding. The number of missing values at baseline are presented, unless there were no missing values.
  2. *.Trajectory groups were estimated by jointly modeling fatigability and mobility over four waves from hospital admission up to six months after discharge.
  3. †.Frailty was assessed by the Frailty Index.
  4. ‡.Depressive symptoms were positive when the Geriatric Depression Score was ≥5.
  5. §.Comorbidity was assessed by the Charlson Comorbidity Index.
  6. |. Fatigability was assessed by the physical subscale of the Pittsburgh Fatigability Scale.
  7. Mobility was assessed by the De Morton Mobility Index.
  8. Abbreviations: ADL, activities of daily living; IQR, interquartile range; LoS, length of stay.
