Figure 6. Validation of TCGA results with other cohorts from the GEO database. Kaplan-Meier survival curves were generated using the data of GEO database to determine the prognosis-related DEGs in TCGA. The Horizontal axis: overall survival time, days; Vertical axis: survival rate. P < 0.05 was used to assess differences in Log-rank test. GEO, Gene Expression Omnibus; TCGA, The Cancer Genome Atlas.
