Interactive MELD Score calculator for end-stage liver disease. Requires the calculator gadget. Usage: {{MELD Calculator}}

MELD Score (Model for End-Stage Liver Disease)
Parameter	Value
Creatinine (mg/dL) — capped at 4.0
Bilirubin (mg/dL)
INR
On Dialysis (2× in past week or CVVHD)	1 No Yes (Cr set to 4.0)
MELD Score

Interpretation — 3-Month Mortality
<10	~2% mortality.
10–19	~6% mortality.
20–29	~20% mortality.
30–39	~53% mortality.
≥40	~71% mortality. Consider transplant evaluation.
