Fig 2. Survival curves for different risk groups.
According to the optimal cut-off value, patients from different cohorts were stratified into the high- or low- risk group. Kaplan-Meier curves were used for survival analyses between different risk groups in different datasets: (A) TCGA-SKCM training dataset. (B) The GEO external validation cohort (GSE65904). (C) The TCGA-UVM external validation cohort.
