SECONDARY outcome
Timeframe: baseline and six weeksA subject is provided with a key matching nine numbers to nine unique symbols. Numbers are then provided in random order and subjects have 120 seconds to match as many numbers with symbols as possible. All correct responses are scored. Scores range from 0 to 135. Scores are later scaled from 1 to 19. Higher scores mean a better outcome.
