KEGG enrichment results demonstrated that infections (malaria, Staphylococcus aureus and Hepatitis B), inflammation (interleukin (IL)‐17 and NF‐κB signalling) and immune regulation (B cell receptor signalling) were the principal pathways whereby the microbiota affected prognosis outcomes (Figure 6H). The gene discussed is NFKB1; the disease is hepatitis B virus infection.
