Fig 3. Comparison of FA (A) and D_av (B) measurements between boxers and healthy control subjects. Compared with healthy control subjects, boxers overall and boxers with normal MR imaging have decreased FA in splenium CC (P < .05), genu CC (P < .005), and posterior IC (P < .05) and increased BD_av (P < .05) and D_av in both the anterior and posterior limbs of IC (P < .05).
