Mean FA, RD and AD (± SD) across all voxels that survived thresholding for the comparison between study groups and control groups.

Mean FA, RD and AD (± SD) across all voxels that survived thresholding for the comparison between study groups and control groups.针对研究组与对照组的对比分析，经阈值筛选后保留的所有体素的各向异性分数（Fractional Anisotropy, FA）、径向弥散（Radial Diffusivity, RD）与轴向弥散（Axial Diffusivity, AD）的均值±标准差（standard deviation, SD）。
