Figure 8. Recurrence-free survival curves stratified by histological diagnosis and PP-DLR-predicted DPHCC status in the training cohort (A and B) and external validation cohort (C and D). Curves were estimated using the Kaplan-Meier method and compared using the log-rank test. PP: Portal venous phase; DLR: deep learning radiomics; DPHCC: Dual-phenotype hepatocellular carcinoma.
