NFKB1 and non-small cell lung carcinoma: We observed that NF-kB expression in nucleus (activation status) was correlated with decreased 5-year OS (OR = 2.12, 95% CI = 1.40–3.21, P = 0.0004), whereas no significant association was observed between cytoplasmic NF-kB expression (inactivation status) and 5-year OS in NSCLC patients (OR = 1.58, 95% CI = 0.54–4.65, P = 0.40) (Fig 7).
