The AUC values indicated that the urinary levels of CCL14 and [TIMP-2]•[IGFBP7] exhibited poor predictive power for 30-day mortality after SA-AKI, with AUC values of 0.623 (95% CI, 0.538–0.704) and 0.593 (95% CI, 0.507–0.675), respectively. This evidence concerns the gene IGFBP7 and acute kidney injury.
