sTILs: stromal tumour-infiltrating lymphocytes, EFS: event-free survival, OS: overall survival, HR: hazard ratio, CIs: confidence intervals. TILs stratified variables: high-TILs (>10%) vs. low-TILs (≤10%). * The multivariate analyses included histological grade (G3 vs. G1/G2), tumour size (T2/T3/T4 vs. T1), lymph node status (N+ vs. N0), and molecular subtype (luminal-A, luminal-B, TNBC) as covariates. Statistically significant p-values are marked in bold.
