Abbreviations: M male, F female, BMI body mass index, ADL activities of daily living (score between 0 and 12, higher scores indicating greater dependency), CRP C-reactive protein, eGFR estimated glomerular filtration ratio, MMSE Mini-Mental State Examination (maximum score of 12 as the best result), LOS length of stay
^aData for ADL at discharge were available in 191 patients (83 patients with and 108 without anaemia)
^bData for hand grip strength were available in 209 patients (104 patients with and 105 without anaemia)
^cData for gait speed were available in 97 patients (42 patients with and 55 patients without anaemia)
