Table 3.
List of white matter regions from tract-based spatial statistics (TBSS) analysis where fractional anisotropy was significantly differently related to Delay Aversion in ADHD compared to non-ADHD adolescents. All locations represent distinct peak regions within three clusters found after statistical corrections for searching the TBSS-derived white matter skeleton using threshold-free cluster enhancement (TFCE), corr p < .05.
