Note: “AD only” refers to participants who had AD in the absence of CT, while “All AD” refers to participants who had AD with or without CT in addition. The same distinction applies for “All CT” versus “CT only.” Specific Learning Disorder encompasses disorders in reading, writing, and mathematics. PDD classification was based on DSM-IV criteria.
