Cox proportional hazard model to detect the effect of the four variables; the overall model was significant (Chi-Quadrat = 38.17; p< 0.001).

	Regression coefficient (95% CI)	Hazard ratio, HR, (95% CI)	Z- score	P-value
CRP level ≥ 5.5 mg/l	1.28 (0.49–2.06)	3.58 (1.64–7.83)	3.2	0.001
NSE level ≥ 22.8 µg/l	1.28 (0.5–2.06)	3.6 (1.66–7.83)	2.4	0.001
MELD-Score ≥11	1.38 (0.62–2.13)	3.97 (1.87–8.45)	3.58	< 0.001
Age ≥ 75 years	1.0 (0.18–1.83)	3.73 (1.2–6.21)	2.7	0.017

CRP, c-reactive protein; NSE, neuron-specific enolase; MELD, model of end stage liver disease; CI, confidence interval.
