These results indicated that the diagnostic value of [TIMP-2]⋅[IGFBP7], as assessed by the AUC, was good (0.75–0.9), thus making it valuable for assessing the risk of AKI; however, the diagnostic value of L-FABP and that of NGAL were poor (0.5–0.75). This evidence concerns the gene IGFBP7 and acute kidney injury.
