Covert hepatic encephalopathy: Agreement and predictive validity of different indices

Figure 1 Cumulative hepatic encephalopathy-free survival. Cumulative hepatic encephalopathy (HE)-free survival over the follow-up period in relation to the combination of electroencephalographic (EEG) and clinical abnormalities (panel A, χ² = 8.2, P = 0.041) and the combination of psychometric hepatic encephalopathy score (PHES) and clinical abnormalities (panel B, χ² = 7.8, P = 0.050) at baseline.

Figure 2 Model for end-stage liver disease scores in patients. Model for end-stage liver disease scores (MELD) in patients grouped based on the combination of electroencephalographic (EEG) and clinical abnormalities (panel A) and the combination of psychometric hepatic encephalopathy score (PHES) and clinical abnormalities (panel B). ^aP < 0.05, ^bP < 0.01 vs post-hoc comparisons.
