Fig. 2From: Comparison of three frailty scales for prediction of prolonged postoperative ileus following major abdominal surgery in elderly patients: a prospective cohort studyReceiver operating characteristic (ROC) curves of mFI-5 and GFI frailty models for predicting PPOI. Frailty evaluated by both mFI-5 (AUC 0.653, 95% CI 0.577–0.730) and GFI (AUC 0.630, 95% CI 0.552–0.707) scales had insufficient accuracy for the prediction of PPOIBack to article page
