In the first column, DSM-5 presentation, followed by columns with number of children, mean age and standard deviation, male to female ratio, followed by the number of children who had been under psychostimulant medication. In the sixth to ninth columns, mean and standard deviation of intelligence quotient (IQ), followed by the mean and standard deviation of the recoded attention total scores 1 to 20 total, cut-off = 7. IQ measured by Wechsler Intelligence Scale for Children (WISC) and WAIS: Wechsler Adult Intelligence Scale, ADHD scores recorded from original scores, details in Materials and methods.
