The demographics of patients and their hormonal status are given. The patients are grouped based on hormonal status and are coded with assigned numbers. All patients were diagnosed with infiltrating ductal carcinomas. ER, estrogen receptor; PR, progesterone receptor; HER2, c-erbB-2; IHC, immunohistochemistry.
