This table includes 743 patients who had at least one biomarker measurement between months 37 and 48 and did not develop HCC before month 37. Twenty-five of these developed HCC between months 37 and 60. Patients are classified according to the maximum biomarker measurement during months 37-48. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV), were calculated comparing patients with and without HCC. Area under the receiver operating characteristic curve (AUC) and P values are based on logistic regression analyses.
