Monovariate analysis showing the association between age, liver function (MELD), abnormal PHES and EEG mean frequency (MDF) with the risk of developing HE-related hospitalisation
| Variables | Beta±SE | p | HR (95% CI) |
| Age | 0.074±0.031 | 0.016 | 1.08 (1.01 to 1.14) |
| MELD | 0.141±0.066 | 0.034 | 1.15 (1.01 to 1.31) |
| Abnormal PHES | 1.035±0.544 | 0.057 | 2.81 (0.97 to 8.17) |
| MDF (EEG) | −0.367±0.155 | 0.017 | 0.69 (0.51 to 0.93) |
