Fig. 3: Association of fractional anisotropy (FA) and the general cognitive performance factor in major depressive disorder (MDD) patients and healthy controls (HC).

FA values were extracted with a threshold of Ptfce-FWE < 0.01 and displayed onto the FMRIB58 template in the x = −36, y = −9, z = 11 planes in MNI space. The scatterplot depicts mean FA values of the significant cluster with a threshold of Ptfce-FWE < 0.05.
