Fig. 3: Comparison between the K-M curves of high-risk groups and low-risk groups.

Progression in 5 years: a for the test set (log-rank test p value < 0.0001, HR = 4.85); b among patients who do not require postoperative interventions (log-rank test p value = 0.0030, HR = 5.01); c among patients who require postoperative interventions (log-rank test p value < 0.0001, HR = 4.34). Death in 5 years: d for the test set (log-rank test p value < 0.0001, HR = 4.57); e among patients who do not require postoperative interventions (log-rank test p value = 0.0443, HR = 4.10); f among patients who require postoperative interventions (log-rank test p value = 0.0036, HR = 3.51). HR hazard ratio (log-rank).
