Figure 2. Risk score and ROC curve of melanoma. (A) Risk score of melanoma patients distributed in ascending order. (B) Survival time and status of melanoma patients in order of increasing risk score. The red dots represent the surviving patients and the blue dots represent dead. (C) The heatmap shows the expression of these six biomarkers in melanoma in order of increasing risk scores. (D) The ROC curve for 1, 2, 5-year survival prediction with AUC value.
