Receiver operating characteristic (ROC) curves showing predictive performance of albumin and ADL, in isolation and in combination, for all-cause mortality in long-lived individuals from the Rugao longevity cohort. The area under the curve (AUC) with 95 % confidence intervals (CIs) for albumin (0.68 [0.61, 0.76], p < .001), for ADL (0.66 [0.58, 0.73], p = .001), and for albumin and ADL in combination (0.73 [0.65, 0.80], p < .001) were documented
