Fig 6. Eigenvalues per region. For UBO, normal-appearing sites (NAS), and controls, mean values for the 3 eigenvalues are plotted for each region. In all regions where UBOs are found,
1,
2, and
3 are higher for UBOs than for NAS and higher for NAS compared with controls. Significant differences between UBO and NAS are indicated by
and between NAS and controls by
