Figure 4:

Bland-Altman plots for intraexamination (blue circle) and interexamination (red triangle) repeatability of semiautomated analysis method–determined volume estimates, respectively, for, A, abdominal SCAT; B, abdominal VAT; C, TAT; and, D, thigh muscle volume ( TMV ). Intraexamination repeatability was evaluated by comparing baseline and repeat 1. Interexamination repeatability was evaluated by comparing baseline and repeat 3. Dashed gray line for each case represents zero bias. Central solid line is at bias level for each case, and upper and lower lines are 95% limits of agreement. Note that, for each compartment, intra- and interexamination results are similar. Bland-Altman metrics are summarized in Table 3.
