Fig. 1From: Association between cancer stem cell gene expression signatures and prognosis in head and neck squamous cell carcinomaStratification of patients with TCGA HNSCC cohort according to the 81 CSC gene expression signatures. a Patients from TCGA HNSCC cohort were classified into CSC-HR (n = 285) and CSC-LR (n = 281) subgroups, by means of hierarchical clustering. b-c The 5-year OS and RFS rates of each group were determined using Kaplan–Meier plots. The CSC-HR subgroup presented significantly lower 5-year OS and RFS rates than those of the CSC-LR subgroup (p = 0.04 and 0.02, respectively). *p < 0.05Back to article page
