Macro partitioning
Reduced muscle mass is a critical phenotypic criterion for malnutrition, measurable via body composition techniques (DXA, BIA, CT) or anthropometrics (calf/arm circumference) when advanced tools are unavailable.
Check muscle mass, not just weight. Use simple measurements like calf or arm circumference if you don't have advanced body composition tools. Low muscle mass is a key sign of malnutrition.
GoodSupportsHIGH confidence
Reduced muscle mass is a phenotypic criterion with strong evidence to support its inclusion in the GLIM consensus criteria.
Why this rating
Consensus based on strong evidence, though measurement methods vary.
