ALB and cholangiocarcinoma: Regression analyses based on the Cox proportional hazards model demonstrated that age at diagnosis (p = 0.02), serum sodium at diagnosis (p = 0.02), creatinine at diagnosis (p = 0.03), bilirubin at diagnosis (p = 0.003), albumin at diagnosis (p = 0.004), and albumin at last entry (p = 0.005) were statistically significant factors associated with death, liver transplantation or cholangiocarcinoma (Table 3).
