Mean SMD by race/ethnicity and sex for patients with nonmetastatic CRC: (A) male; (B) female. The estimated marginal means and conference intervals are from generalized linear models adjusted for age and BMI (*P value of mean difference <0.05 based on Caucasians as the reference group). The interaction term between sex and race/ethnicity was tested with the likelihood ratio test and multivariate linear regression model (P < 0.001). CRC, colorectal cancer; HU, Hounsfield unit; SMD, skeletal muscle radiodensity.
