Parameters associated with survival time.

LT, liver transplantation; HR, hazard ratio; 95% CI, 95% confidence interval; high, exceeding the optimal cut-off point; low, equal to or below the optimal cut-off point; MELD, Model for End-Stage Liver Disease; MELD-Na, sodium MELD§,† “Low” and “high” refers to values below and above the optimal cut-off point as defined using the Youden index, respectively. The reference groups were patients with low serum copeptin and §low MELD score or †low MELD-Na score.Optimal cut-off points and results of univariate (A) and multivariate (B) Cox proportional hazard regression analysis assessing factors associated with liver transplantation or death awaiting liver transplantation in relation to time of follow-up in cirrhotic patients registered at the waiting list for liver transplantation (n = 61).
