Validation and evaluation of clinical prediction systems for first and repeated transarterial chemoembolization in unresectable hepatocellular carcinoma: A Chinese multicenter retrospective study

Figure 2 Receiver operating characteristic curves for evaluating the radiological correlations of the scoring systems. A: Correlations between radiological response and predicting scores; B: Correlations between radiological response and risk stratifications based on the predictive systems for first transarterial chemoembolization. HAP: Hepatoma Arterial-embolization Prognostic; mHAP: Modified HAP; 6&12: Six-and-twelve criteria.
