Clinical characteristics are expressed as mean ± SD values for continuous variables and as n (%) for categorical variables.
P-values were derived from the independent two-sample t-test for continuous variables and from the chi-square test for categorical variables.
*P < 0.05.
‡P < (0.05/16).
BMI, body mass index; ASMI, appendicular skeletal muscle index; DM, diabetes mellitus; HTN, hypertension.
