Abbreviations: AF, arcuate fasciculus; IFOF, inferior frontal occipital fasciculus; ILF, inferior longitudinal fasciculus; IQ, intelligence quotient.
Scanning centre, age and full scale IQ, were all included as covariates.
^aP-values are significant at a level <0.05 after Holm‐Bonferroni correction.
