Significant differences of GMD in each cluster and receiver operating characteristic (ROC) curve for each pair of groups. Classifier results showed GMD of cerebellar vermis tonsil cluster in SZ-CD vs HCs could differentiate SZ-CD from controls (sensitivity,92.5%;specificity75%, a), the left cerebellum cluster (anterior lobe and posterior lobe) in SZ-NCD vs HCs could distinguish between SZ-NCD vs controls(sensitivity,90.5%;specificity,77.8%, b) and all SZ versus all controls (sensitivity,90.5%,specificity70.6%, b), left supplementary motor area (SMA)cluster(left SMA, bilateral precentral gyrus) in SZ-CD vs SZ-NCD could differentiate SZ-CD from SZ-NCD (sensitivity,83.3%;specificity,81.2%, c), GMD of cerebellar vermis tonsil cluster in SZ-CD vs SZ-NCD could differentiate SZ-CD from controls (sensitivity,92.5%;specificity75%, d) GMD, gray matter density; SZ-CD, schizophrenia with cognitive deficits; SZ-NCD, schizophrenia without cognitive deficits; HCs, healthy controls
