Relationships between frailty and 3-year mortality. (a) Kaplan-Meier survival analyses showing the impact of frailty (FI-MDS) on mortality (n = 116). The outcome of mortality was considered met in participants who had died after 36 months (n = 69) or who had been discharged to a higher level of care (n = 6). Individuals who were frail (FI-MDS ≥0.27) had a significantly higher 3-year mortality (P < 0.005) than those who were non-frail. (b) Receiver Operating Characteristic (ROC) curve for the prediction of 3-year mortality (n = 116) from the FI-MDS. The area under the curve (AUC) was 0.651 (p = 0.007) with 77% sensitivity and 49% specificity to predict 3-year mortality based on a FI-MDS ≥ 0.27
