  1. a Obtained from ACNOVA for quantitative variables and chi-square for qualitative variables (P < 0.05 significant)
  2. b Muscle mass lower than 5.45 (kg/m2) for women and 7.26 (kg/m2) for men were considered low [24]
  3. c Abnormal muscle strength was defined according previous study [28]
  4. d Gait speeds lower than 0.8 m/s were considered abnormal [24]. Model1: Adjusted for energy, age and sex
