Volumes normalized by head size using the FSL’s SIENAX tool volumetric scaling factor. Pearson’s correlation coefficient is provided in case the assumptions of the linear regression model are satisfied. When these assumptions are not satisfied, Spearman’s rank correlation coefficient is provided and noted by a. After FDR correction, using level 0.08, the cutoff p-value for significance of a single comparison was 0.048 (for the AIS group) and 0.016 (for the PVI group) marked in bold
