Bland Altman plots of DXA versus MRI measures of L1L4 and L2L4 fat.
Figure 4A shows L1L4 region. Figure 4B shows L2L4 region. Difference between measures represented as log values. The central dashed line represents the mean difference between measures. The upper and lower dashed lines represent the 95% limits of agreement (±2SDs of the mean difference). The solid line represents the line of best fit from linear regression.
