Fig. 1From: Prognostic significance of the albumin-to-globulin ratio for upper tract urothelial carcinomaROC curve analyses for (a) CSS and (b) OS. The optimal cutoff value of AGR was estimated as < 1.25 by maximizing the Youden’s index [Sensitivity − (1 − Specificity)] for both endpoints of CSS and OS. Abbreviations: AGR = albumin-to-globulin ratio; CSS = cancer-specific survival; OS = overall survival; ROC = receiver operating characteristicBack to article page
