F2 and infection: If the clinical examination found that the patient was apathetic and had hepatic diabetes, the likelihood of concurrent HE increased to 0.155; if the patient’s total bilirubin was greater than 51.3 mmol/L and prothrombin time was longer than 18 s, the probability of concurrent HE increased to 0.341; if the patient showed any of the factors of infection, electrolyte disorders, or hepatorenal syndrome, the probability of concurrent HE exceeded 0.60 (i.e., 0.615, 0.834, and 0.867, respectively).
