Multivariable logistic regression model of bedside postoperative parameters at the time of biomarker assessment with and without the (TIMP-2)^*(IGFBP7) for risk assessment of AKI, use of RRT, 28-days mortality and AKI 2,3.

*Likelihood-ratio test (comparing the fit of both models) AKI, acute kidney injury; RRT, renal replacement therapy; IGFBP7, insulin-like growth factor-binding protein 7; TIMP-2, tissue inhibitor of metalloproteinase; MAP, mean arterial pressure, AUC, area under the curve; CI, coincidence interval; OR, odds ratio. Multivariable logistic regression model of bedside postoperative parameters at the time of biomarker assessment with and without the (TIMP-2)*(IGFBP7) for risk assessment of AKI, use of RRT, 28-days mortality and AKI 2,3.
