Brain map of linear regression-derived coefficients regarding the relationship between repetitive and restricted behaviors and interests-related factors and neuroanatomic structures. A Representation of the linear regression-derived coefficient obtained for each cortical volume (at left) and subcortical volume (at right) considering Factor 1. Extreme values of the linear regression-derived coefficients are represented in blue (<  − 1) and in red (> + 1). P values < 0.05 before FDR correction were obtained for the left amygdala, left putamen and right putamen volumes; B Representation of the linear regression-derived coefficient obtained for each cortical volume (at left) and subcortical volume (at right) considering Factor 2. Extreme values of the linear regression-derived coefficients are represented in blue (<  − 1) and in red (> + 1). P values < 0.05 before FDR correction were obtained for the left parietal, left putamen and right putamen volumes; C Representation of the linear regression-derived coefficient obtained for each cortical volume (at left) and each subcortical volume (at right) considering Factor 3. Extreme values of the linear regression-derived coefficients are represented in blue (<  − 1) and in red (> + 1). P values < 0.05 before FDR correction were obtained for the left amygdala, left putamen and right putamen volumes
