Figure 3. Establishment of neutrophils-related genes (NRGs) cluster subtypes. (A) Principal component analysis (PCA) plot of the overall expression of all samples before batching. (B) PCA plot of the overall expression of all samples after batching. (C–E) Process and results of consistency cluster analysis, which classified the data into NRGclusters A and B. (F) Survival curves of patients with NRGclusters A and B. The prognosis of patients with NRGcluster B was significantly better than that of patients with NRGcluster A. (G) PCA plot of NRGclusters A and B. (H) The expression of neutrophil-associated genes in NRGclusters A and B, most neutrophil-associated genes are upregulated in NRGcluster A.
