Model for End-Stage Liver Disease (MELD) 3.0 for ages 12 and older

MELD 3.0 = round(1.33*(Female) + 4.56*ln(Serum bilirubin) + 0.82*(137 - Sodium) - 0.24*(137 - Sodium)*ln(Serum bilirubin) + 9.09*ln(INR) + 11.14*ln(Serum creatinine) + 1.85*(3.5 - Serum albumin) - 1.83*(3.5 - Serum albumin)*ln(Serum creatinine) + 6)

Notes

• The MELD utilizes natural log transformation such that any value less than 1 is automatically given a lower limit value of 1 to prevent generating a negative score.
• The lower limit of serum sodium (Na) is capped at 125, and the upper limit is capped at 137.
• The lower limit of serum albumin is capped at 1.5, and the upper limit is capped at 3.5.
• The upper limit of serum creatinine is capped at 3.
