Model for end-stage liver disease-Na score or Maddrey discrimination function index, which score is best?

Figure 1 Comparison of Maddrey discrimination function index and model for end-stage liver disease-Na in predicting mortality at 30 and 90 d in alcoholic hepatitis. For 30-d mortality the area under the curve (AUC) was 0.763 for Maddrey DFI and 0.784 for MELD-Na (P = 0.82). For 90-d mortality the AUC was 0.685 for Maddrey DFI and 0.8710 for MELD-Na (P = 0.041). MELD: Model for end-stage liver disease; DFI: Discrimination function index.
