Abstract: Objective

·To establish and evaluate a screening model of liver cirrhosis patients complicated with minimal hepatic encephalopathy (MHE).


·A total of 404 patients with liver cirrhosis who were hospitalized from June 2017 to November 2019 were selected as the research subjects, and the clinical data of them were collected. Based on Logistic regression analysis and artificial neural network (ANN), the MHE screening models were established, and the discriminant ability of the two models was evaluated and compared.


·The Logistic regression model showed that age, history of diabetes mellitus, infection, renal insufficiency, nutritional risk, total bilirubin>24 μmol/L, blood ammonia>47 μmol/L and international normalized ratio (INR)≥1.5 were the significant risk factors (all P<0.05). The area under the curve (AUC) of receiver operator characteristic curve (ROC curve) of ANN model and Logistic regression model were 0.814 and 0.737 (Z=4.208, P=0.000), respectively. The sensitivities were 72.4% and 69.9%, and the specificities were 76.7% and 67.8%, respectively.


·The ANN model is more effective than the Logistic regression model in MHE screening.

Key words: minimal hepatic encephalopathy (MHE), artificial neural network (ANN), screening model
