A systematic review and meta-analysis done by Zhang et al. [13] which included the studies of Yamashita et al. [22] and Dai et al. [23] reported diagnostic ability of pNGAL with AUCs of 0.94 (95% CI, 0.88–0.97) and 0.92 (95% CI, 0.84–0.96) respectively for plasma NGAL to predict AKI in septic patients similar to our findings.
