Robustness of findings
comorbidity, ADHD, autism
REGRESSION
We conducted additional analyses to determine the robustness of our findings. Specifically, we examined whether medication effects on brain-behavior association are stable with respect to head motion, exclusion of IQ as covariates in the regression model. We also examined whether results were influenced by comorbidity with autism in children with ADHD. Results from these analyses replicated our main findings, highlighting the robustness of our findings (Supplementary Materials).
