Subsequently, we constructed a nomogram based on these DMlncRNAs in the training set and included the following factors: age, ATRX mutation status, sex, PTEN mutation status, tumour grade, diagnosis type, tumour staging, IDH1 R132 mutation status, EGFR mutation status, TP53 mutation status and the risk scores of the five DMlncRNAs (Figure 4C). This evidence concerns the gene TP53 and neoplasm.
