**Figure 8.** **The prognostic nomogram for predicting OS and DSS probability.** (**A**) The prognostic nomogram for predicting OS probability by the multivariable Cox regression model via the four statistically significant predictors, such as SERP1, N stage, Melanoma ulceration and Breslow depth. (**B**) The prognostic nomogram for predicting DSS probability. (**C**) The time-dependent ROC curves of OS for 1, 3, 5 year. (**D**) The time-dependent ROC curves of DSS for 1, 3, 5 year. (**E**) The calibration curve of OS for 1, 3, 5 year. (**F**) The calibration curve of DSS for 1, 3, 5 year.
