Fig. 2

Computed tomography (CT) scans were used to assess the pectoralis muscle area and density. a, the CT axial slice above the aortic arch level shows the pectoralis muscle segmentation (red, pectoralis major muscle; blue, pectoralis minor muscle). b and c, differences between pectoralis muscle densities are depicted in CT images
