Kaplan-Meier survival curves for the ANN model on Cohort-2 (red is the high-risk subgroup and blue is the low-risk subgroup). The cutoff value used to define the high-risk subgroup was chosen based on results on Cohort-1. The number of patients remaining at each labelled time point in each risk group is shown below the plot.
