Figure 4. Decreased fractal dimension (FD) in aNSCLP compared with controls. Regions with intergroup differences are shown on lateral views. Two-sample t-test for every pair in the groups was used; statistical significance was P<0.05, FWE-corrected. Color bars indicate T-values. The 3D brain map shows the spatial location of intergroup different regions, and the boxplot below shows the surface index values for the two groups.
