Stratified analysis of the ALDH2 interaction revealed an increased odds of triple negative breast cancer in women who consumed ≥ 7 drinks per week (OR (95% CI) = 4.41 (1.79, 10.86), p = 1.26 × 10–3), and decreased odds in women who consumed < 7 drinks per week (OR (95% CI) = 0.57 (0.36, 0.89), p = 0.013). The gene discussed is ALDH2; the disease is triple-negative breast carcinoma.
