highly significantp-value < 5x10 -324
While seemingly less profound, the difference between the distributions of correlation of intra and extra module genes is highly significant (p-value < 5x10 -324 , Kolmogorov–Smirnov test for equal distributions) with a tendency of the genes belonging to the same module to have higher correlations (p-value < 5x10 -324 , Wilcoxon sum rank test).
