  1. Auto: Automated quantification of liver/muscle attenuation, respectively.
  2. Manual 1: Manual segmentation of the majority of the liver/muscles, respectively.
  3. Manual 2: Manual segmentation of three dorsal liver ROIs and one elliptical muscle ROI, per leg, respectively.
  4. Correlations: Linear correlation coefficient (R) between automated and manual measurements.
  5. *p-value lower than 0.001 between all three measurements.
