Patient outcomes stratified by HER2 status. A-BĀ Kaplan-Meier analyses indicate disease-free-survival (DFS) (A) and breast cancer-related overall survival (OS) (B) according to HER2 status in all 447 patients. Green and red lines indicate patients with IHC(3+) and IHC(2+)/FISH(+) tumors, respectively. C-DĀ DFS (C) and OS (D) in the 314 patients who received adjuvant chemotherapies in combination with anti-HER2 drugs. E-F DFS (E) and OS (F) in the 129 patients who did not receive any chemotherapy
