Inclusion criteria: decompensated liver cirrhosis; age >18 years old. Exclusion criteria: other cancers except primary liver cancer; mental illness; pregnant and lactating women; incomplete medical records. A total of 6648 patients were finally included in the study, who were divided into infection group (n=3430) and non-infection group (n=3218) according to whether they were co-infected or not. 70% (4654 cases) of the patients included in the study were randomly selected as the training set to construct the prediction model, and the remaining 30% (1994 cases) were used as the test set for internal validation.
