Table 4.

Correlations of diffusion metrics with language ability as measured with the CELF-4 are shown for the arcuate fasciculus. Regression coefficients and coefficient standard errors for MD, AD, and RD are scaled ×10−7 and FA is scaled ×10−4. The p-values are reported to one significant figure and p-values under 0.05 are marked with an asterisk and in bold. MD: Mean diffusivity; FA: fractional anisotropy; AD: axial diffusivity; RD: radial diffusivity.
