  1. SD standard deviation, No number, y years, d days, BMI body mass index, IQR interquartile range, SNAQ short nutritional assessment questionnaire, ADL activities of daily living, NRS numeric rating scale, FAC functional ambulation categories
  2. aCalculated as weight in kg divided by height in m2
  3. bUse of 5 or more different medications
  4. cRange of 0–31, with a higher score indicating more or severe comorbidity
