Figure 3. 5-year melanoma-specific survival analyses in training, validation and combined cohorts.

Melanoma-specific survival in different subgroups of primary melanomas was analyzed by the Kaplan-Meier survival model. Patients in the ML subgroup showed poorer prognosis than patients in the NML subgroup in the training cohort A. poor survival for patients in the ML subgroup was found in the validation cohort B. and combination cohort C. Log-rank P value is indicated in the graphs.
