We previously reported that women polymorphic for the methylenetetrahydrofolate reductase (MTHFR) gene were less likely to have cervical intraepithelial neoplasia (CIN) 2 or 3 (odds ratio [OR] 0.40, 95% confidence interval [CI] 0.21-0.78, P = 0.007). In the present study, we tested whether this protective association is modified by circulating riboflavin status in the same study population.
