Cortical thickness analysis among patients and healthy controls groups. a Significant differences among groups were identified using ANCOVA with age and sex as covariates (* p < .05, corrected for multiple comparisons with LSD). The right Heschl’s gyrus (labeled in green) showed significant difference in cortical thickness among three groups. (AH < NH, HC, AH = Hallucinating patients with schizophrenia, NH = Non-hallucinating patients with schizophrenia, HC = Healthy controls. Error bars represent SDs). b The cortical thickness of right Heschl’s gyrus was negatively correlated with the severity of auditory verbal hallucinations, as assessed by AHRS scores
