Static prognostic scores in AH.

Score	Variables	Significance	Severity cutoff			Mortality observed
Maddrey’s DF	Bilirubin, PT	Evaluates risk of mortality at 30 days	<32: non-severe		≥32: severe	At 30 days: • DF <32: < 10% • DF ≥32: > 20–30%
MELD	Bilirubin, INR, creatinin	Evaluates risk of mortality at 90 days	<21: non-severe		≥21: severe	At 90 days: • MELD <21: <20% • MELD ≥21: ≥20% The probability of 90-day mortality according to MELD score can be calculated with the next formula: P = e(−4.3+0.16 × MELD) / [1+e(−4.3+0.16 × MELD)])
GAHS	Bilirubin, INR, urea, WBC, age	Evaluates risk of mortality at 28 days and 84 days	<9: nonsevere		≥9: severe	At 28 days: • GAHS <9: 13% • GAHS ≥9: 54% At 84 days: • GAHS <9: 21% • GAHS ≥9: 60%
ABIC	Bilirubin, INR, creatinin, age	Evaluates risk of mortality at 90 days and 1 year	<6.71: low risk	6.71–8.99: intermediate risk	≥9: high risk	At 90 days: • ABIC <6.71: 0% • ABIC 6.71–8.99: 30% • ABIC ≥9: 75% At 1 year: • ABIC <6.71: 2.9% • ABIC 6.71–8.99: 35.7% • ABIC ≥9: 66.7%
