Preoperative albumin levels predict prolonged postoperative ileus in gastrointestinal surgery

Figure 1 Receiver operating characteristic curves of preoperative albumin for predicting prolonged postoperative ileus in patients who underwent gastrointestinal resection. ROC: Receiver operating characteristic; AUC: Area under the curve. AUC: Null hypothesis: True area = 0.5.
