Figure 1.

Relative pre-seizure change of centrality values of nodes in the different modules. Non-hatched/hatched bars represent median values over predictive/non-predictive nodes (median pre-seizure centrality values referenced against median centrality values from seizure-free periods). Blue/black numbers on top represent the number of predictive/non-predictive nodes in each module (${\mathcal{C}}^{\text{S}}$ strength centrality; ${\mathcal{C}}^{\text{B}}$ betweenness centrality; ${\mathcal{C}}^{\text{C}}$ closeness centrality; ${\mathcal{C}}^{\text{E}}$ eigenvector centrality; “total” refers to the sum of these nodes). As betweenness centrality often yields values of 0, calculating a relative difference is not always possible, therefore we refer to the median absolute value which here amounts to 0.005 independent of the module (SOZ: $\mathcal{S}$, neighbours: $\mathcal{N}$, others: $\mathcal{O}$).
