Supplementary Fig. S2 The prognostic values of AFP and MDK levels for HCC patients. Supplementary Fig. S3.Expression of serum MDK in another independent cohort (cohort B) from Egypt. Supplementary Fig. S4. Logistic Regression Model to combine information of MDK and AFP for prediction of HCC in the learning cohort A (n=252): Comparison of AUROC for diagnosis HCC through logist regression model I, serum MDK and AFP. Supplementary Fig. S5. Positive predictive value (PPV) and negative predictive value (NPV) for identifying HCC patients through serum MDK according to different prevalence. Supplementary Fig. S6.
