Table 2: The Conners’ ContinuousPerformance Test (CPT-II) of the placebo (R) and intervention (Y) groupsin participants with ADHD1.
1 Values are expressed as the mean ± SD.Data from 7 participants with attention deficit hyperactivity disorder (ADHD). *p < 0.05 compared to baseline by pair t-test. †p < 0.05 compared to R by pair t-test. RT, reaction time; ISI, inter-stimulus interval; SE, standard error.
