Kaplan–Meier curves of triple-negative breast cancer patients (n = 176) according to tumor-infiltrating lymphocytes (TILs) and platelet-to-lymphocyte ratios (PLRs). Patient outcomes according to patient groups, based on TIL and PLR are shown. Group 1, TIL-high/PLR-low (n = 31); Group 2, TIL-high/PLR-high (n = 43); Group 3, TIL-low/PLR-low (n = 60); and Group 4, TIL-low/PLR-high (n = 42). a Distant metastasis-free-survival (DMFS) and, c overall survival (OS) according to TILs. Dark blue and red lines indicate TIL-high patients (Groups 1 and 2), and TIL-low patients (Groups 3 and 4), respectively. b Comparison of DMFS and, d OS, according to the four patient groups
