The mean change from baseline after 4 weeks of treatment in total cognitive score on the BACS was calculated as a weighted average of T-scores (normalized for age) from BACS subtests including Verbal Memory, Digit Sequencing, Token Motor, Symbol Coding, Semantic Fluency, Letter Fluency, and Tower of London. The minimum and maximum values possible for this composite T-score of the change from baseline were -131 and 131, respectively. Higher values (positive changes from baseline) indicate better performance.
