A univariate Cox analysis was first performed for the training group patient data, which identified the following as the most significantly related factors to ALD: relapse, cirrhosis, liver cancer, ascites, encephalopathy, haemoglobin (HB), platelet count (PLT), total bilirubin (TBIL), albumin (ALB), creatine (Cr), prothrombin time-International Standardization Ratio (PT-INR), Na, and MELD ≥21 (Table 2). This evidence concerns the gene ALB and liver cancer.
