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.
