NFKB1 and cancer: The pooled ORs of the included case-control studies revealed a statistically significant association between the NFKB1 promoter −94ins/del ATTG polymorphism and cancer risk across the four genetic models ins/ins versus del/del, OR = 1.47, 95%, CI = 1.11—1.93; dominant model, OR = 1.26, 95%  CI = 1.03—1.53; recessive model, OR = 1.26, 95%  CI = 1.05—1.51; and ins allele versus del allele, OR = 1.19, 95%, CI = 1.05–1.35 (Table 2, Figure 2).
