The immune status and immune cell infiltration in the high-risk and low-risk groups were evaluated by principal component analysis (PCA) and Tumour Immune Estimation Resource (Timer). A PCA map based on genome-wide expression set. B PCA map based on the immune-related gene expression set. C PCA map based on immune-related lncRNA set. D PCA map based on the 6-lncRNA signature. E The relationship between the risk score and infiltration abundance of six kinds of immune cells was analysed based on the 6-lncRNA signature: macrophages, neutrophils, dendritic cells, CD8 T cells, CD4 T cells and B cells
