In the overall sample, we did not find a significant interaction between alcohol and menopausal status; however, when considering different breast cancer subtypes defined by hormone receptors, there was a significant interaction between menopausal status and alcohol for hormone receptors-positive (ER+ or PR+) breast cancer, and no evidence of interaction for hormone receptors-negative (ER- or PR-) breast cancer. This evidence concerns the gene PGR and breast carcinoma.
