  1. Notes
  2. aaccording to cut-off-values by EWGSOP2: low grip strength: men < 27 kg, women < 16 kg; low gait speed < 0.8 m/s; high CRT time > 15 s; low muscle mass ASM/h2: men < 7 kg, women < 5,5 kg; sarcopenia classification: probable: low grip strength and/or high CRT time; confirmed: low grip strength and/or high CRT time and low ASM/h2; severe: low grip strength and/or high CRT time and low ASM/h2 and low gait speed
  3. baccording to cut-off-values by FNIH: low muscle mass ASM/BMI: men< 0.789m2, women< 0.512m2 and low grip strength: men< 26 kg, women< 16 kg.
