  1. Quantitative variables are expressed as median [25th - 75th centiles] and categorical variables as N (%)
  2. (n= /) indicates the number of patients in each group in case of missing data
  3. MNA-SF, Mini Nutritional Assessment-Short Form; ADL, activities of daily living scale; MMSE, Mini Mental State Examination; GDS, Geriatric Depression Scale
  4. aHypertension was defined as blood pressure ≥140/90 mmHg or treatment for hypertension
  5. bCreatinine clearance was calculated using the abbreviated Modification of Diet in Renal Disease formula, glomerular filtration rate (mL/min/1.73 m2) = 186.3 × [creatinine (μmol/L) /88.4] -1.154 × [Age (years)]-0.203 × 0.742 (if female) × 1.21 (if black)
  6. cTimed Get-Up-and-Go test >20 s or patient unable to perform the test
