Open the original (DOI 10.5152/pcp.2025.241035)- What it measures
- The ADHD group was 137 combined type and 63 inattentive type participants. The control group was matched for age and sex.
- What it does not show
- The control group is about a quarter the size of the ADHD group, so comparisons between groups are less precise.
