Kamath 2001 model for end-stage liver disease (MELD) from creatinine, bilirubin,
Kamath 2001 model for end-stage liver disease (MELD) from creatinine, bilirubin, INR, and etiology. meld = round(3.8*ln(bilirubin_mg_dL) + 11.2*ln(INR) + 9.6*ln(creatinine_mg_dL) + 6.4*etiology). etiology is 0 if cholestatic or alcoholic, else 1. Does not floor labs at 1.0 and does not include dialysis (later UNOS/OPTN). Not MELD-Na. Not a transplant listing or allocation order.
