Diagnostic performance of frailty and comorbidity measures for mortality outcomes in patients with all the measures available (n = 4 945). (A) Receiver operating characteristics (ROC) curves for in-hospital mortality; (B) Harrell’s C-statistics from Cox models for 30-day and 6-month mortality. CFS, HFRS, CCI, and eFI were considered as continuous variables in all the models. CFS = Clinical Frailty Scale; HFRS = Hospital Frailty Risk Score; CCI = Charlson Comorbidity Index; eFI = electronic frailty index.
