Kaplan–Meier survival curves showing comparison of overall survival between high (orange) and low (blue) infiltration (inf.) of immune/inflammatory cells. P-values obtained from log-rank test. The ‘x’ and ‘+’ represent censoring and failure, respectively. The proportions of 5-year survival with 95% confidence intervals (in parentheses) are shown. *Ratio of CD68⁺HLA-DR⁺ M1 macrophages to CD68⁺ pan-macrophages, **ratio of FOXP3⁺CD4⁺ Tregs to CD4⁺ T cells.
