ICA-based risk score (RS) can predict patient survival. Performance of the risk score on the TCGA discovery patient cohort (a). Validation of the risk score on the independent cohort composed of 44 metastatic melanoma patients (b). Cox regression log hazard ratio (LHR) together with its 95% C.I. and log rank p-value are reported. In order to visualize the results as Kaplan-Meier curves, patients were divided into two groups by their RS (low risk – blue and high risk – red)
