Figure 4. A) Cytochrome P450 2E1 (CYP2E1) RsaI/PstI polymorphism was significant associated with the risk of chronic alcoholic pancreatitis (CAP) [odds ratio (OR) =1.62, 95 % confidence interval (CI): 1.12-2.34; p =0.011] but not among the acute alcoholic pancreatitis (AAP) group for a dominant model (c2c2+c1c2 vs c1c1); B) CYP2E1 RsaI/PstI polymorphism was significant associated with the risk of CAP (OR =1.62, 95 % CI: 1.17-2.24, p =0.004), but not among the AAP group for an allelic contrast model (c2 vs c1).
