Fibrinogen-to-Albumin Ratio Predicts Contrast-Induced Nephropathy in Patients after Emergency Percutaneous Coronary Intervention

Figure 1

Receiver operator characteristic (ROC) curve analysis. ROC curve analysis demonstrated that an FAR cutoff value of 0.106 was optimal, exhibiting 65.5% sensitivity and 78.9% specificity for detecting contrast-induced nephropathy (CIN). The C-statistic was 0.721 (0.682–0.757).
