Fig. 2From: Integrated bioinformatics analysis for the identification of idiopathic pulmonary fibrosis–related genes and potential therapeutic drugsKEGG enrichment analyses of 18 hub genes. All significant KEGG pathways were performed using the DAVID online tool with the cutoff criterion of FDR < 0.05. The color of each bubble represents the FDR for that pathway, with blue indicating greater significance. The rich factor refers to the proportion of enriched genes for each pathwayBack to article page
