Group differences in post treatment FA structural connectivity of the left amygdala. A. HBOT group (blue) patients showed increased FA of the amygdala tracts. Histogram and a distribution fit. B. Scatterplot of the change in FA, and the change in the BSI-18 score. The r is the Pearson's correlation coefficient. The 95% prediction interval is presented as a green line; FA, fractional anisotropy.
