Kamath PS et al. A model to predict survival in patients with end-stage liver disease. Hepatology. PMID: 11172350. Pre-2016 MELD = 9.57×ln(creatinine) + 3.78×ln(bilirubin) + 11.2×ln(INR) + 6.43, rounded to an integer and capped at 40. Laboratory values below 1 are set to 1, creatinine is capped at 4 mg/dL, and dialysis at least twice in the past week sets creatinine to 4. (2001)
