The clustering coefficient C and small world index S were correlated with history of epilepsy for an average degree k = 3 (Kendall's Tau (C) = −0.346; p = 0.013 and Kendall's tau (S) = −0.360; p = 0.009 respectively) (see figure 5). The correlation of epilepsy duration with the small world index S remained significant after Bonferroni correction, determining correlations to be significant when p<0.013 was reached. The clustering coefficient C showed a correlation with epilepsy duration at a significance level of p = 0.013, which was the same as the cut-off point for significance after Bonferroni correction. An example of a network distribution over the ECoG grid is shown in figure 6.
