Fig. 2From: Effects of polymorphic cytochrome P450 2A6 genotypes on chemoprevention against colorectal tumors in single Japanese cohort using daily low-dose aspirin: insights into future personalized treatmentsEffects of CYP2A6 haplotypes and genotypes on aspirin chemoprevention for colorectal tumor recurrence in the total cohort and the nonsmoker subset of Japanese J-FAPP IV study participants. Data shown in Panel A were taken from Ishikawa et al. [15]. The preventive effects of aspirin were evaluated based on the numbers of polyps that had developed to a size of ≥5 mm (J-FAPP IV) observed after 8-months. Odds ratios are shown with respect to the reference (placebo) groupBack to article page
