- Tract density is expressed in tracts/mm3; Tract length in millimeters (mm); Diffusivity measures—AD, MD, and RD—in 10–3 mm2/s; FA is dimensionless. ANOVA (or the nonparametric Kruskal–Wallis test *) p values for the comparison of each DTI metric between regions are shown on the last column—statistically significant results are highlighted in bold
