Preoperative computed tomography-based risk stratification model validation for postoperative pancreatic ductal adenocarcinoma recurrence

Figure 1 Kaplan Meier survival curves for patients stratified by risk group. The low-risk group showed significantly better survival outcomes than the moderate and high-risk groups, whereas the high-risk group exhibited the poorest prognosis. Differences in survival among the groups were statistically significant (log-rank test, P < 0.001), indicating the predictive value of the risk score for patient prognosis. A: Risk score 1 from Reader 1; B: Risk score 2 from Reader 2.
