CD8A and breast cancer: We found that the B cell fraction > 0.025 (Figure 3a), M0 macrophage fraction < 0.05 (Figure 3b), CD8+ T cell fraction > 0.25 (Figure 3c), and NK T cell fraction > 0.075 (Figure 3d) are ideal conditions, as characterized by lower SHAP values on the y-axis, for enhanced ≥5-year survivability chances for breast cancer patients.
