  1. Data represent median values (interquartile range) for continuous variables and numbers (percentage) for categorical variables. No significant difference was observed for any of the parameters.
  2. BMI = body mass index. bADL = basic activities of daily living. iADL = instrumental activities of daily living. CRP = C-reactive protein. Hb = hemoglobin. GFR = glomerular filtration rate calculated with the Cockcroft & Gault formula. GS = grip strength. FR = fatigue resistance. GW = grip work. LBM = lean body mass. *(mean of both hands).
