Prognostic value of IMMT in BC. A–N Kaplan–Meier survival analysis of relapse-free survival (RFS) based on IMMT expression. “Auto select best cut off” algorithm function was used to divide low/high groups in all BC patients (A), PAM50 subtype with basal (B), HER2-E (HER2-enriched) (C), luminal A (D) and luminal B (E), grade 1 (F), grade 2 (G), grade 3 (H), patients undergoing any chemotherapy (I), patients undergoing adjuvant chemotherapy (J), patients undergoing neoadjuvant chemotherapy (K), patients undergoing tamoxifen only (L), nodal status negative (M), and nodal status positive (N). O and P forest plot illustrating the HR of high IMMT, the 95% CI when harboring various immune cell contents (O) and TMB extent (P)
