Receiver operating characteristic curve and AUC showing the diagnostic performance of sCyC for CI‐AKI detection. AUC=0.856 (P<0.001). AUC indicates area under the curve; CI‐AKI, contrast‐induced acute kidney injury; sCyC, serum cystatin C.
Portion of patients with Mehran risk score greater than 6 and incidence of MAEs in the CI‐AKIsCyC group and the non‐CI‐AKIsCyC group. CI‐AKIsCyC indicates contrast‐induced acute kidney injury defined by serum cystatin C; MAEs, major adverse events. **P<0.01.
Portion of patients with Mehran risk score greater than 6 and incidence of MAEs in patients stratified by the composite of sCyC and sCr. CI‐AKI indicates contrast‐induced acute kidney injury; MAEs, major adverse events; sCr, serum creatinine; sCyC, serum cystatin C. ***P<0.001.
