Selection results and prediction accuracy for the ASD risk. The six selected AAL regions are the right postcentral gyrus (PoCG-R), the right inferior frontal gyrus triangular part (IFGtriang- R), the right median cingulate and paracingulate gyri (DCG-R), the right superior frontal gyrus (SFGmed-R), the supplementary motor area (SMA-R) and the right heschl gyrus (HES-R). Nvoxel is the total number of selected voxels. P-Sens and P-Spec represent sensitivity and specificity in prediction of the ASD risk via a ten-fold cross validation
