CI, confidence interval; HU, Hounsfield unit; IMAT, intermuscular adipose tissue; IMAT%, percentage of IMAT; MNA-SF, mini nutritional assessment short form; OR, odds ratio; SMA, skeletal muscle area; SMD, skeletal muscle radiodensity; SMI, skeletal muscle index.
These indicators were included in the multivariate logistic models independently, which adjusted for age, cardiovascular disease, diabetes, MNA-SF score, and albumin. In the whole sample, these multivariate logistic models further adjusted for sex.
