Fig. 2From: Copeptin in acute decompensation of liver cirrhosis: relationship with acute-on-chronic liver failure and short-term survivalAssociation of the estimated probability of death using the chronic liver failure-consortium organ failure (CLIF-C OF) score at 28 days (a) and 90 days (b) of follow-up, stratified according to serum copeptin concentration. The optimal cut-off point of serum copeptin in predicting 28- and 90-day mortality was defined using the Youden IndexBack to article page
