Fig. 5From: From comorbidities of chronic obstructive pulmonary disease to identification of shared molecular mechanisms by data integrationGenes and Pathways relating COPD and Digestive Alterations Disease Group (DG8). The figure shows the association between genes (a), Gene Ontology (b) and KEGG (d) gene-sets for those ICD9 codes included in DG8; the description of ICD9 codes is provided in panel (c). A dark (light) blue square denotes if the association between disease and pathway or gene was computed as significant when using either mapping1_DG or mapping2_DG (only mapping1_DG). Top 10 genes or gene-sets are shown; and then only ICD9 codes with at least association with an item are shown. The ICD9 codes are ordered using the number of associations with genes or gene-sets in the total set; from lower (left) to higher (right). The last two elements denote the association with DG8 and COPD. Similar information for Biocarta and Reactome is depicted in Additional file 12: Figure S8. In panel (c), those ICD9 codes shown in all other panels are in boldBack to article page
