CST3 and acute kidney injury: Furthermore, the value of the endostatin–clinical risk prediction model was superior to those of the NGAL–clinical risk and cystatin C–clinical risk prediction models in predicting nonrecovery from AKI, which was supported by both NRI (endostatin vs NGAL p = 0.027, endostatin vs cystatin C p = 0.044) and IDI (endostatin vs NGAL p = 0.021, endostatin vs cystatin C p = 0.006) analysis (Additional file 1: Table S1).
