Enrichment of known cancer genes in cross-validation testing of MaxLink method. The enrichment is the frequency of cancer genes in the retrieved set relative to their frequency in the entire database. Overall, the enrichment of cancer genes with one or more links is just above 5. Restricting the retrieved set to genes with a higher maxlink score produces a proportionally increased enrichment. The enrichment levels at high maxlink scores are somewhat variable due to small amounts of data.
