Figure 6. Tumor purity combined with SFTPC-related risk score to evaluate the prognosis of LUAD patients. (A) The immune and stromal scores of LUAD patients in the TCGA_LUAD cohort, grouping based on the risk score. (B) The tumor purity of LUAD patients in the TCGA_LUAD cohort, grouping based on the risk score. (C–H) Kaplan-Meier curves of the OS of LUAD patients in different subgroups from TCGA_LUAD (C, D), GSE72094 (E, F), and GSE41271 (G, H) cohorts.
