Table 1 MELD and MELD variants compared in our study

MELD

MELD = 3.78 × ln[serum bilirubin (mg/dL)] + 11.2 × ln[INR] + 9.57 × ln[serum creatinine (mg/dL)] + 6.43

MESO index

[MELD/Na (mmol/L)] × 10

I-MELD

MELD + (0.3 × age)−(0.7 + Na) + 100

MELD-Na

[0.025 × MELD × (140−Na)] + 140 sodium < 125 is calculated at 125. Sodium > 140 is calculated at 140

UKLED

5.395 × In INR + 1.45 In creatinine + 3.3 In bilirubin−81.565 In Na + 435
