Figure 3. Construction of molecular subtypes based on malignant cell receptor ligand genes. (A) Single factor Cox analysis HR distribution map of malignant cell associated receptor gene set. (B) CDF curve of TCGA cohort sample. (C) CDF Delta area curve of TCGA cohort sample, the horizontal axis represents the number of clusters K, and the vertical axis represents the relative change of the area under the CDF curve. (D) Sample cluster heat map of consensus K = 2. (E) KM curve of prognosis relationship between two subtypes of TCGA. (F) KM curve of prognosis relationship between two subtypes of ICGC-JP.
