PSM adjusted OS and BCSS of BCBM patients with surgical treatment (Stratified by molecular subtype). Kaplan–Meier (K–M) survival analysis: A OS of BCBM patients with HR + /HER2− subtype; B OS of BCBM patients with HR + /HER2 + subtype; C OS of BCBM patients with HR−/HER2 + subtype; D OS of BCBM patients with HR−/HER2− subtype; E BCSS of BCBM patients with HR + /HER2− subtype; F BCSS of BCBM patients with HR + /HER2 + subtype; G BCSS of BCBM patients with HR−/HER2 + subtype; H BCSS of BCBM patients with HR−/HER2− subtype. OS overall survival, BCSS BC-specific survival, BCBM BC brain metastases, HR ±  hormone receptor positive/negative, HER2 ±  human epidermal growth factor receptor 2 positive/negative, PSM propensity score matching, HR hazard ratio, CI confidence interval
