A remarkable correlation was discovered between quartiles of ALB and AST and hospital mortality in total patients with PPH and patients with PPH and without liver disease (for total patients with PPH, ALB: p = 0.006; AST: p = 0.012; for patients with PPH and without liver disease, ALB: p = 0.023; AST: p = 0.042) (Table 3). The gene discussed is ALB; the disease is liver disorder.
