Comparison of bicor, Pearson correlation and Spearman correlation based signed adjacency in 8 empirical data sets. Each panel show the −log10 transformed 5 best gene ontology enrichment p-values of all modules identified using each type of adjacency. Error bars stand for 95% confidence intervals. On top of each panel is a p-value based on multi-group comparison test. All three types of correlation are similar in terms of GO enrichment.
