+# Model for End-stage Liver Disease (MELD) score
+
+#### MELD score is a numerical value that is used to predict the 3-month mortality prediction risk of a patient. It is also used to prioritize patients for liver transplantations with higher score indicating a more urgent need.
+### Parameters needed
+| Parameter | Unit |
+| --------- | ---- |
+| Serum Bilirubin | mg/dL |
+| Serum Creatinine | mg/dL |
+| International Normalized Ratio (INR) | - |
+### MELD Score interpretation table:-
+
+| Score range | Mortality risk |
+| ----------- | -------------- |
+| less than 9 | Low risk (under 1.9%) | 
+| 10 to 19 | Low to Moderate (6.0% - 19.6%) |
+| 20 to 29 | Moderate risk (19.6% - 52.6%) | 
+| 30 to 39 | High risk (52.6% - 71.3%) |
+| more than 40 | Extremely high risk (71.3% - 100%) |
+
+### Formula to calculate MELD:-
+The MELD score is calculated using the following formula:-
+$$
+\textbf{MELD} = (9.57 \times \ln(\text{Serum Creatinine})) + (3.78 \times \text{Serum Bilirubin}) + (11.2 \times \text{INR}) + 6.43
+$$
+
+### Notice:-
+The MELD score is not considered accurate for advanced liver diseases. Other calulcators like MELD-Na should be used before taking clinical decisions
