Highest AUC values for AKI risk stratification had plasma interferon γ-induced protein 10 (IP10) (0.73), cystatin C (0.71), and monokine induced by interferon-γ (MIG) (0.70) (Fig 4), although these results were not statistically different from plasma creatinine (0.69). This evidence concerns the gene CXCL9 and acute kidney injury.
