Correlations between tumour occurrence and intrinsic regional brain activity per tumour subtype. (A) The correlation between regional tumour occurrence of all IDH-mutant, 1p/19q-codeleted gliomas on the x-axis and average regional intrinsic brain activity of the healthy controls on the y-axis (error bars indicate SD per region), for broadband power (left), offset (middle) and slope (right). Axis titles are identical for all plots. B and C show the same correlations for all IDH-mutant, 1p/19q non-codeleted gliomas and IDH-wild-type gliomas, respectively. *Statistically significant using the spin test.
