Figure 6. Correlation analysis of LDHA expression with TME in multiple cancers. The correlation of LDHA expression with stromal score, immune score, and ESTIMATE score in ACC (A–C), LIHC (D–F), LUAD (G–I), and PAAD (J–L). Gray brown background indicates no significant correlation between the gene expression and the corresponding index (p >0.05). Light background indicates that the gene is significantly correlated with the corresponding index (p <0.05). R represents correlation value, R >0 means positive correlation, R <0 means negative correlation.
