Relation between MGMT, ABCG2 or ABCB1 promoter methylation and selected SNPs. (A) Bivariate analysis of the association between the MGMT promoter methylation and the MGMT C-56 T polymorphism (Wilcoxon test, p = 0.02). (B) Bivariate analysis of the association between the ABCG2 promoter methylation and the ABCG2 C421A polymorphism (Kruskal-Wallis test, p = 0.30). (C) Bivariate analysis of the association between the ABCB1 promoter methylation and the ABCB1 C3435T polymorphism (Kruskal-Wallis test, p = 0.63).
