Evaluation of MELD score and Maddrey discriminant function for mortality prediction in patients with alcoholic hepatitis. Monsanto P, Almeida N, Lrias C, Pina JE, Sofia C. BACKGROUND/AIMS: Maddrey discriminant function (DF) is the traditional model for evaluating the severity and prognosis in alcoholic hepatitis (AH). However, MELD has also been used for this purpose. We aimed to determine the predictive parameters and compare the ability of Maddrey DF and MELD to predict short-term mortality in patients with AH.
