However, no significant association between CYP2E1 Dra I polymorphism and urinary cancer susceptibility in either dominant model (CD+CC vs. DD, OR = 0.913, 95% CI = 0.791–1.051, P = 0.202) or the allele model (C vs. D, OR = 0.978, 95% CI = 0.847–1.117, P = 0.748) was showed. Here, CYP2E1 is linked to cancer.
