Nested model comparisons of GWC age effects mapped onto FreeSurfer default common group template (‘fsaverage’). a Comparison of the linear vs. quadratic model including all age effects and age-by-group interactions. b Comparison of the quadratic vs. cubic model including all age effects and age-by-group interactions. Left panel shows the difference map resulting from the model comparison. F-values (blue to red) indicate voxels where the more complex model provided a better fit than the more reduced model (F-statistic, unthresholded). Right panel indicates random-field theory (RFT)-based, cluster-corrected (p < 0.05) difference maps in goodness of fit (based on F-statistic). Here, the colourscale relates to F-statistic within significant clusters where the quadratic model provided a significantly better fit than the linear model
