Development and validation of a risk score for predicting mortality after resection of primary hepatocellular carcinoma
Figure 3. X-tile analysis of the risk score in the training cohort (A1, A2, A3) and the Kaplan-Meier survival curves for the risk groups in the validation cohort (B). The cut-off points for the risk groups were determined based on A2 as <5 (low risk), 5–10 (medium risk), and >10 (high risk).
