TP53 and breast cancer: Overall, a slightly association of TP53 p.Arg72Pro polymorphism with the risk of breast cancer was observed for the dominant (OR = 1.09, 95% CI = 1.02–1.16, P = 0.01, Fig. 2) and additive (OR = 1.09, 95% CI = 1.01–1.17, P = 0.03, Fig. 3) models, but not for the recessive model (OR = 1.07, 95% CI = 0.97–1.18, P = 0.19, Fig. 4).
