Fig. 2: The plots of FA, MD, and RD profiles of significant alterations in UF among ADD, ADND, and HC groups (FDR correction, p < 0.05, green for HC, blue for ADND, and red for ADD).

A FA of left UF, B MD of left UF, C RD of left UF, D FA of right UF, E MD of right UF, F RD of right UF. The solid line represents the mean and the shaded area represents the standard deviation. The red bars under the profile indicate the regions of significant difference among the three groups. The histograms show statistically significant differences in FA, MD, and RD of UF nodes among the ADD, ADND, and HC groups. FA fractional anisotropy, RD radial diffusivity, MD mean diffusivity, UF uncinate fasciculus.
