  1. TMPST Theory of Mind Picture Stories Task, SZ patients with schizophrenia, HC healthy controls, SD standard deviation.
  2. aSignificant level of analysis of covariance (ANCOVA) with estimated IQ as a covariant
  3. bBoth the BACS raw scores and Z-scores of the patients’ group were listed in the table; as the mean Z-score was set to 0 and the standard deviation was set to 1 in the healthy control group, only raw scores were listed
