For each subject, two sides of NAA/(Cho + Cr) ratios are divided into large and small sides. The asymmetry index (AIs) scatters in a wide range. In the control group, the AIs is 0.77 on the average. The plot shows that the relationships among three groups in large and small sides are quite parallel. There is a trend of lowering NAA/(Cho + Cr) ratios in TLE + FC, but no statistical interaction between groups and sides was found (P = .272).
