Between-group differences and age-by-group interactions for GWC. a Clusters with significantly reduced GWC (RFT-based, cluster corrected, p < 0.05) in ASD compared to controls (blue to cyan colourscale) while controlling for the effects of age and age-related interactions (i.e. main effect of group). b Clusters with significant linear age-by-group interactions (RFT-based, cluster corrected, p < 0.05). c Clusters with significant quadratic age-by-group interactions (RFT-based, cluster corrected, p < 0.05). Note. Significant positive age-by-group interactions are displayed in red to yellow, significant negative age-by-group interactions are displayed in blue to cyan
