Interaction term was significant bilaterally. When interaction terms were significant bilaterally, we probed the interaction for the tract with the larger effect size. AB = antisocial behavior; CU = callous-unemotional traits. UF-R = right uncinate fasciculus; UF-L = left uncinate fasciculus; CG-R = right cingulate gyrus; IFOF-R = right inferior occipital fasciculus; IFOF-L = left inferior occipital fasciculus; SLF-L = left superior occipital fasciculus; ILF-R = right inferior longitudinal fasciculus; ILF-L = left inferior longitudinal fasciculus; ATR-L = left anterior thalamic radiation. All models controlled for participant age and race. Models were ran using centered variables of AB (Range − 9.80–37.20; M 0.14; SD 8.19; Uncentered Range: 0–47; Uncentered M 9.94) and CU traits (Range − 1.84–3.24; M − 0.016; SD 0.96; Uncentered Range − 1.90–3.18; Uncentered M − 0.07). Region of significance (RoS) indicate the centered value at which the simple slopes are significantly different from zero (i.e., UF-L FA: at centered values of CU traits >0.36, the simple slope is significantly different from zero). The last column indicates the percentage of the sample that exceeds the threshold of CU traits at which the simple slope is significantly different from zero.
