Admission to Postdischarge | N with no CFS Change | N with -1 CFS Change | AUC Predicting -1 CFS Change (95% CI) | Change in FI with Highest J | J (Sensitivity, Specificity) |
All | 1,565 | 1,819 | 0.68 (0.66–0.70) | −0.032 | 0.27 (0.66, 0.61) |
Males | 716 | 855 | 0.67 (0.64–0.69) | −0.025 | 0.25 (0.75, 0.50) |

Note: Only patients who maintained or changed CFS by 1 level were included in this analysis. AUC = area under the ROC curve; CFS = Clinical Frailty Scale; CI = confidence interval; FI = Frailty Index; J = Youden Index value for the change in FI that best predicts a one-level change in CFS.
