Venn diagrams comparing enrichment methods for prostate cancer data. Set enrichment was determined using the logistic regression model. Panels i, ii, and iii compare the sets identified as enriched for genes (G) or metabolites (M) alone to a joint enrichment method; (i) Univariate naïve, (ii) Fisher's method (p-value sum), (iii) 2-df Wald test. Panel iv compares the three joint tests.
