Is an estimated glomerular filtration rate better than creatinine to be incorporated into the end-stage liver disease score?

Table 5 The difference between the model for end-stage liver disease and model for end-stage liver disease-modification of diet in renal disease-6 scores of differentially obtained estimated glomerular filtration rate for the prediction of in-hospital mortality

Statistical comparison was performed with logistic regression analysis. MELD: Model for end-stage liver disease; eGFR: Estimated glomerular filtration rate; MDRD: Modification of diet in renal disease; MDRD-4: 4-variable MDRD; MDRD-6: 6-variable MDRD.
