Figure 6. The role of tumor clusters of necroptosis-related lncRNAs in immunotherapy. (A) The necroptosis-related lncRNAs were divided into three subtypes according to the consensus clustering analysis. (B) The Kaplan–Meier analyzed the difference in the clusters. (C) The Sandel diagram of risk groups and the clusters. (D, E) The PCA of risk groups and clusters. (F, G) The t-SNE analysis of risk groups and clusters. (H–J) The comparison of immune-related scores in risk groups. (K) The heat map of immune cells with tumor clusters by different analytical methods. (L) The difference of 28 checkpoints expression in clusters. PC, principal component; tSNE, T-distributed stochastic neighbor embedding. * P < 0.05; ** P < 0.01; *** P < 0.001.
