FIGURE 2.

Violin plots showing mean regional blood–brain barrier (BBB) Ktrans in 10 brain regions in APOEε3 (black, n = 19) and APOEε4 (red, n = 17) carriers. Group median is shown as solid horizontal line. No significant difference was found by analysis of covariance (ANCOVA) (mean difference). Regions: left hippocampus, right hippocampus, left white matter anterior cingulate cortex, right white matter anterior cingulate cortex, left anterior cortex, right anterior cortex, anterior parahippocampal gyrus, posterior parahippocampal gyrus, left hippocampus subcortical probe, and right hippocampus subcortical probe
