Sample subcomponent type and survival analysis

The necroptosis-related lncRNA gene set described above was used for subtype glioma patients. Consistency analysis by using the ConsensusClusterPlus R package (v1.54.0), the maximum number of clusters is 6, and 80% of the total sample is drawn 100 times, clusterAlg = ‘hc’, innerLinkage = ‘ward.D2’. With the use of the Kaplan–Meier survival analysis of the different groups of samples from TCGA dataset, a comparison among different groups was made by log-rank test. HR (95% CI) and the median survival time (LT50) for different groups were determined. Meanwhile, the association between tumor subtypes and high-risk groups was also validated. The ‘Rtsne’ and ‘ggplot2’ packages were used to visualize data using principal component analysis (PCA) and t-distributed stochastic neighbor embedding (t-SNE).
