Significant clusters in both hemispheres: cluster size in mm², P values from the Monte Carlo simulation (P < .05) and clustering as cluster-wise probability (CWP), resulting from the vertex-wise comparison of mean cortical thickness, area and local gyrification index and NCRS scores. Age, gender, olanzapine equivalents, Positive and Negative Symptoms Scale, Abnormal involuntary movement scale, and Barnes Akathisia Rating Scale scores were used as covariates. Significant clusters that survived the Bonferroni correction (P < .0027) are displayed in bold font.
