Figure 2. Trp-related dual classifications and the enrichment of pertinent biological functions. (A) Harmonized matrix heatmap delineating a pair of distinct clusters; (B) Survival analysis among the two subtypes; P value was calculated based on Log-rank test; (C) Differences in the PCA analysis among the two clusters; (D) Disparities in expression levels of TMRGs related to clinical characteristics within the two unique subtypes; (E) Disparities in the immune infiltration between the two distinct clusters.
