Identification of Differences in Body Composition Measures Using 3D-Derived Artificial Intelligence from Multiple CT Scans across the L3 Vertebra Compared to a Single Mid-Point L3 CT Scan

Table 1

Characteristics of body composition for all patients and by sex in CRC patients using only the mid-L3 slice.
