A correlation matrix was calculated for these genes, using Pearson Product-Moment Coefficient, defined as r x , y = ∑ i = 1 n ( x i − x ̄ ) ( y i − y ̄ ) ( n − 1 ) δ x δ y The values of Pearson correlations above 0.3 are statistically highly significant (p-value < 0.00001 after Bonferroni correction for multiple testing [ 85 ]).
