Table 1 Associations between CCND1 amplification status, cyclin D1 protein expression and clinicopathological variables in all patients

From: Effects of cyclin D1 gene amplification and protein expression on time to recurrence in postmenopausal breast cancer patients treated with anastrozole or tamoxifen: a TransATAC study
