Prognostic role of plasma level of angiopoietin-1, angiopoietin-2, and vascular endothelial growth factor in hepatocellular carcinoma

Figure 2 Factors correlated with plasma level of angiopoietin-1, angiopoietin-2 and vascular endothelial growth factor in hepatocellular carcinomas patients with their interrelationship. The heat map showing a red background indicates a positive correlation, the blue background indicates negative correlation, and the numbers in the box indicate rho (ρ). AFP: Alpha-fetoprotein; Ang-1: Angiopoietin-1; Ang-2: Angiopoietin-2; BCLC: Barcelona clinic liver cancer; BMI: Body mass index; MELD: Model for end stage liver disease; NLR: Neutrophil-lymphocyte ratio; PLR: Platelet-lymphocyte ratio; VEGF: Vascular endothelial growth factor.
