  1. 1according to cut-off-values by EWGSOP2: low grip strength: men <27 kg, women <16 kg; low gait speed <0.8m/s; high CRT time >15s; low muscle mass ASM/h²: men <7 kg, women <5,5 kg;
  2. 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. ² according to cut-off-values by FNIH: low muscle mass ASM/BMI: men<0.789m², women<0.512m² and low grip strength: men<26kg, women<16kg
  4. *low grip strength and low muscle mass are already adjusted for sex
