Variable	Regression coefficient	95 % CI of regression coefficient	β	p value
GFAP	−0.013	−0.021 to −0.006	−0.251	<0.001
MELD	−0.131	−0.297 to 0.034	−0.134	0.118

R² = 0.357. p values < 0.05 are highlighted in bold font. GFAP, glial fibrillary acidic protein; MELD, model for end-stage liver disease; OHE, overt hepatic encephalopathy; PHES, psychometric hepatic encephalopathy score.
