^aCensored: 299; recurrence: 299; death: 16.

^bAdjusted for patient, tumour and treatment characteristics (age, neoadjuvant chemotherapy, breast-conserving surgery followed by re-excision, multifocality, multicentricity, size of primary tumour, total number of involved lymph nodes, lymphovascular invasion, primary histologic type, pathologic subtype, estrogen and progesterone receptor status, adjuvant chemotherapy, and adjuvant radiation therapy).

CPM = contralateral prophylactic mastectomy.
