Kim 2021 MELD 3.0 from sex, bilirubin, INR, creatinine, sodium, albumin, and dialysis. meld_3 = round(1.33*(female) + 4.56*ln(bilirubin) + 0.82*(137-Na) - 0.24*(137-Na)*ln(bilirubin) + 9.09*ln(INR) + 11.14*ln(creatinine) + 1.85*(3.5-albumin) - 1.83*(3.5-albumin)*ln(creatinine) + 6). Creatinine 1.0-3.0 (dialysis 3.0); bilirubin and INR floor 1.0; sodium 125-137; albumin 1.5-3.5. Not original MELD or MELD-Na. Not a transplant listing or allocation order.
