### Korean ADHD Rating Scale (K-ARS) Life Science Identifiers  
Table 3 summarizes the K-ARS scores of the experimental and control groups, and Figure 3 shows the change in scores 14 d and 28 d from the baseline time. There was no significant difference in the repeated measures ANOVA or baseline-corrected covariate analysis between the experimental and control groups. Significant decreases were reported on day 28 compared with the baseline for the total score of the experimental group (\(p\) < 0.001), K-ARS attention deficit (\(p\) = 0.001), and K-ARS hyperactivity (\(p\) < 0.001). Significant decreases were reported on day 28 compared with the baseline for the total score of the control group (\(p\) = 0.009), K-ARS attention deficit (\(p\) = 0.026), and K-ARS hyperactivity (\(p\) = 0.005).
