NFKB1 and cancer: Consistently, NFKB1 -94 ins/del ATTG polymorphism was significantly associated with decreased cancer susceptibility among HB population in all genetic models, among which the most obvious is for dominant model (DD+DW vs. WW: OR = 0.85, 95% CI = 0.77–0.95, P = 0.003), and weakest for recessive model (DD vs. DW+WW: OR = 0.86, 95% CI = 0.74–0.99, P = 0.04).
