Note: Results of comparison between individuals with first-episode psychosis (FEP) and healthy controls (HC), after jack-knife sensitivity analysis. Results were thresholded at P < .005 uncorrected (equivalent to P < .05 corrected), peak threshold of 1, extent threshold of 10. Seed networks included default mode network (DMN), and salience network (SN). dMPFC, dorsomedial prefrontal cortex; PCC, posterior cingulate cortex; TPJ, temporoparietal junction; MPFC, medial prefrontal cortex; dACC, dorsal anterior cingulate cortex; MTG, medial temporal gyrus; v. precuneus, ventral precuneus; DC, dorsal caudate; sVC, superior ventral caudate; iVC, inferior ventral caudate; OFC, orbitofrontal cortex; SDM-Z, SDM test statistic. SDM-estimate, effect size created by SDM. Coordinates are MNI standard stereotaxic space. Voxels = number of 1 mm × 1 mm × 1 mm voxels. Jack-knife survival rate refers to number of iterations the peak survived out of the total number of iterations, during the jack-knife sensitivity analyses.
