Table 3 Results of three statistical tests to investigate the role of specific anatomical structures in the predictions. * and ** mark significant and highly significant p-values (\(\alpha = 0.05\) and \(\alpha = 0.01\)). Bonferroni correction is applied to the Wilcoxon signed-rank tests (\(\alpha _{{\rm ind}}=0.00714\) and \(\alpha _{{\rm ind}}=0.00142\)). The tests compare patches containing anatomical structures with ones that show background.
