Figure 7. Association between disulfidptosis score and tumor microenvironment factors in pan-cancer. (A) Heatmap of the correlation between disulfidptosis score and pan-cancer stromal score, immune score, estimate score and tumor purity. Red represents positive correlation, blue represents negative correlation, and the darker the color, the stronger the correlation. *p< 0.05, ** p< 0.01, and *** p< 0.001, ****p< 0.001. (B–E) Tumor purity (B), stromal score (C), estimate score (D), and immune score (E) are illustrated.
