From: Trait aspects of auditory mismatch negativity predict response to auditory training in individuals with early illness schizophrenia

  3. a Repeated measures ANOVA, Treatment Group x Time interaction
  4. b Cognitive measures were transformed to z-scores using normative data of healthy samples. Global Cognition is the average z-score across all measures from the MATRICS
  5. c Group mean and standard deviation (SD) mismatch negativity (MMN) age-corrected z-scores for each deviant type averaged over the six fronto-central leads (F3, Fz, F4, C3, Cz, C4)
  6. Statistically significant p-values are formatted in bold
