From: Factors associated with frailty in primary care: a prospective cohort study
ROC of the proposed model for identifying frailty in primary care. Receiver operating characteristic curve for the final model to predict frailty-related outcomes, based on age, Timed Up and Go time and polypharmacy status. The curve represents the relationship between sensitivity and 1-specificity for all potential cut-off points of the diagnostic test under study. The area under the curve (AUC), a measure of the discriminatory power of the test, is 0.822. The cut-off point that maximises sensitivity and specificity (i.e., 76 %) is 0.288
