PC analysis, overall survival rate and analysis of TME of LC in 2 robust clusters. A The optimal cluster number was two using the ConsensusClusterPlus package. B Principal component analysis (PCA) was also an intuitive way to assess the optimal k. C Overall survival analysis between cluster 1 and cluster 2 of LC. D–F Comparison of stromal score, immune score and estimate score between two clusters in the TME of LC samples. G Violin diagram of the proportion of 22 types of immune cells involved in two clusters in LC samples. H The infiltration of immune cells involved in cluster1 and cluster2 in LC samples with 7 algorithm. *p < 0.05; **p < 0.01; ***p < 0.001
