Cox proportional hazards regression model test for the OS values of all patients.

Group M, MBC; Group A, pre/peri-menopausal FBC; Group B, post-menopausal FBC; ER, estrogen receptor; PR, progesterone; HER2, human epidermal growth factor receptor-2.
Cox proportional hazards regression model test for the OS values of all patients.

M组：转移性乳腺癌（Metastatic Breast Cancer, MBC）；A组：绝经前/围绝经期女性乳腺癌（Female Breast Cancer, FBC）；B组：绝经后女性乳腺癌（Female Breast Cancer, FBC）；雌激素受体（Estrogen Receptor, ER）、孕激素受体（Progesterone Receptor, PR）及人表皮生长因子受体2（Human Epidermal Growth Factor Receptor-2, HER2）。针对所有患者的总生存期（Overall Survival, OS）指标开展Cox比例风险回归模型检验。
