Fig. 1: Grey matter volume (GMV) differences between SSCE and CON groups.

a, b Schematic (a) and statistical results (b) of GMV differences between SSCE and CON after 2-week and 4-week modeling. c Difference in grey matter volumes of whole brain and prefrontal subregions. The statistical threshold is set as p < 0.05. Asterisks indicate significance from two-sample t-tests (*p < 0.05; ** p < 0.01; ***p < 0.001).
