The Brief Assessment of Cognition in Schizophrenia (BACS) was used to evaluate cognitive impairment, as measured by the mean change from baseline after 2 weeks of treatment in the composite score. The BACS composite score was calculated by averaging scores from the BACS subtests, including Verbal Memory, Digit Sequencing, Token Motor, Symbol Coding, Verbal Fluency (Semantic Fluency and Letter Fluency) and Tower of London. The possible minimum and maximum scores for change from baseline at two weeks of treatment for the endpoint are -111.5 and 111.5, respectively.
