Table 4 The ICC of muscle parameters between the two observers (\(\:\stackrel{-}{x}\)±s). SMA, skeletal muscle area; SMD, skeletal muscle density; IMAT, intermuscular adipose tissue; SFA, subcutaneous fat area in abdominal wall; SFD, subcutaneous fat density in abdominal wall.

From: Intermuscular adipose tissue affected muscle density more than intramuscular adipose tissue content with opportunistic screening at abdominal CT
