Figure 3 Time-dependent receiver operating characteristic curves for comparisons. A: Comparisons among prognostic systems in first transarterial chemoembolization; B: Comparisons among prognostic systems in repeated transarterial chemoembolization. AUROC: Area under receiver operating characteristic curve; HAP: Hepatoma Arterial-embolization Prognostic; mHAP: Modified HAP; 6&12: Six-and-twelve criteria; ART: Assessment for re-treatment with TACE; ABCR: Alpha-fetoprotein, BCLC stage, Child-Pugh and Response.
