  1. HR, hazards ratio; CI, confidence interval; ADL, activities of daily living scale
  2. aHazards ratios and confidence intervals were estimated using Cox proportional models simultaneously adjusted for all variables listed in the table
  3. bper additional impaired ADL item
  4. c>3 Kg within the 3 months preceding admission
  5. dper increase by 1 standard deviation
  6. eCreatinine 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)
