Then, we ranked the relative importance of the 40 features (Figure 3A) and identified the 10 most important predictors, including K, low-density lipoprotein (LDL), D-dimer (D-D), RBC, alanine aminotransferase (ALT), albumin (ALB), monocyte (Mono), tumor size, triglyceride (TG), and age. Here, ALB is linked to neoplasm.
