Computed tomography-based radiomics to predict early recurrence of hepatocellular carcinoma post-hepatectomy in patients background on cirrhosis

Figure 6 Kaplan-Meier curve analysis of the overall survival of patients stratified based on the best Youden index after hepatectomy. The high-risk and low-risk groups had scores > 0.53 and < 0.53, respectively. A: In the training cohort, the median overall survival (OS) was 3.00 and 8.08 years for the high-risk and low-risk groups, respectively (P < 0.0001); B: In the validation cohort, the median OS was 2.83 and 5.25 years for the high-risk and low-risk groups, respectively (P = 0.028).
