Fig. 4. Violin plots comparing the distribution of PBSI scores between individuals at CHR-P and healthy controls, across surface area (PBSI_SA), cortical thickness (PBSI_CT), and subcortical volume (PBSI_SV); the mid-point indicates the group mean.

PBSI Person-Based Similarity Index, SA surface area, CT cortical thickness, SV subcortical volume. All three phenotypes demonstrate significantly lower similarity in PBSI profiles in the CHR-P group compared with healthy controls, across PBSI_SA (p < 0.01), PBSI_CT (p < 0.01), PBSI_SV (p < 0.01).
