Figure 3. Identification of endoplasmic reticulum stress (ERS)-related molecular subtypes. (A) Heatmap of consensus matrix when k = 2. (B) The principal component analysis could remarkably distinguish ERGcluster A and B. (C) The survival curve of ERGcluster A and B. (D) The expression difference of endoplasmic reticulum stress-related genes (ERGs) between ERGcluster A and B. (E) GSVA analysis. (F) GSEA analysis. (G) ssGSEA analysis.
