Comparison scoring model of severe viral hepatitis and model of end stage liver disease for the prognosis of patients with liver failure in China

Table 1 Scoring model of the prognosis of patients with severe viral hepatitis

Variables	Scores
	0	1	2	3
Clinical type	-	Chronic	Subacute	Acute
HE	-	Grade 1-2	Grade 3	Grade 4-5
PTA (%)	≥ 80	60-80	40-60	< 40
Serum sodium (mmol/L)	≥ 135	125-135	120-125	< 120

HE: hepatic encephalopathy; PT: prothrombin time; PTA: prothrombin activity. PTA= (control`PT-8.7) ÷ (patient`s PT-8.7) × 100%.
