From: SOD1 is a novel prognostic biomarker of acute kidney injury following cardiothoracic surgery
Comparison of prognostic value for urinary SOD1 and serum creatinine. Urinary concentrations of SOD1 (AUC: 0.85) showed improved ability to predict the progression to severe AKI when compared with serum creatinine concentrations at the time of sample collection (AUC: 0.69), the change in serum creatine from collection to peak creatinine value (AUC: 0.71), and the established AKI biomarker NGAL (AUC: 0.74). Optimal cutoff values, sensitivity, specificity, positive predictive values, negative predictive values, likelihood ratio, and p-values are presented for each biomarker
