In stratified analyses, however, AA men had greater disparity of NF‐κB expression associations with prostate cancer by disease aggressive status (NF‐κB decreased risk for nonaggressive disease but showed a suggestive positive association with aggressive disease) and age (NF‐κB decreased risk for older cases but showed a suggestive positive association with prostate cancer for younger cases). The gene discussed is NFKB1; the disease is prostate carcinoma.
