Significant BER per-allele associations by polyp sub-site.

aExcludes 21 individuals who characterized their race/ethnic group as "other."; bPer-allele ORs and 95%confidence intervals computed using multinomial logistic regression assuming a log-additive model and adjusting for age, exam date, sex, clinic, study phase, and race among all study participants; cCrude p-value; dCrude p-value corrected for multiple comparisons using PACT; ePathway wide (ppathway) p-value based on Bonferroni correction of PACT for the number of BER gene regions investigated (N = 14); fp-value for heterogeneity by polyp subsite.
