BD = bipolar disorder; dl = dorsolateral; dm = dorsomedial; FL = frontal lobe; HPC = hippocampus; l = left; OC = occipital cortex; p = posterior; PL = parietal lobe; PUT = putamen; r = right; RM = relative motion; SS = somatosensory; SZ = schizophrenia.
Subgroup analyses show results of the t test between centrality means of patients with schizophrenia (n = 34) and the other patients in the schizophrenia group (i.e., those with schizoaffective disorder, schizophreniform disorder and psychosis not otherwise specified, n = 37), patients with BDI (n = 25) and other patients in the BD group (i.e., those with BDII/BD not otherwise specified, n = 18), and the effect of diagnosis on centrality with other schizophrenia patients excluded. Positive t values shows higher mean centrality in patients with schizophrenia and BDI compared with the other subgroups. The main effect of motion is shown in each cluster (positive and negative t values show an increased or decreased centrality with increasing motion, respectively, and the effect of diagnosis with motion added as an additional covariate to the model.
