![]() The NCDR risk model tended to underestimate the risk of CIN, while the Mehran model was more evenly calibrated. ![]() The NCDR risk model showed superior risk discrimination for predicting CIN (NCDR c-index 0.75, 95% CI 0.72–0.78 vs. Risk models were compared regarding discrimination (receiver operating characteristic analysis), net reclassification improvement (NRI) and calibration (graphical and statistical analysis). Predictions of Mehran and NCDR-AKI risk models and clinical events of CIN and need for dialysis were assessed in a total of 2067 patients undergoing coronary angiography with or without percutaneous coronary intervention. However, its performance in comparison to more contemporary National Cardiovascular Data Registry-Acute Kidney Injury (NCDR-AKI) risk models remains unknown. ![]() The Mehran risk model is the gold-standard for CIN risk prediction. Contrast-induced nephropathy (CIN) is a major adverse event in patients undergoing coronary angiography. ![]()
