Multivariate Cox regression analyses indicated that tumor differentiation and RelB expression had statistical significances, with hazard ratio (HR) of 2.115 for tumor differentiation (95% CI 1.044–4.286, p = 0.038) and 2.996 for RelB (95% CI 1.848–6.047, p = 0.002). Here, RELB is linked to neoplasm.
