Different approaches to handle gene-set redundancy.

Gene-set redundancy correction methods typically utilize modified gene-sets (Modified gene-sets) or rely on a modified enrichment test (Modified test), but usually require hierarchically structured gene-sets; consequently, they usually do not support gene-sets from resources other than Gene Ontology. Other methods offer different types of visualization support, adopting a hierarchical, tabular or network organization of gene-sets. These methods usually allow a broader choice of gene-set sources and enrichment tests. The table also indicates whether the method supports comparison of different enrichment results.
