Figure. Association of Biomarkers (Expressed per Milliliter of Urine Concentration) Across 4 Serum Creatinine (SCr) and Cystatin C (CysC) Acute Kidney Injury (AKI) Categories.

Figure

Four boxplots (middle line is the median, and upper and lower stems are 95th and 5th percentiles, respectively) of first postoperative biomarker concentrations across 4 groups of patients. From left to right in each graph, the groups did not fulfill any criteria for AKI by SCr or CysC, only fulfilled AKI criteria by SCr but not CysC criteria, only fulfilled AKI criteria by CysC but not SCr criteria, and fulfilled both SCr and CysC for AKI. IL-18 indicates interleukin 18; KIM-1, kidney injury molecule 1; L-FABP, liver fatty acid–binding protein; and NGAL, neutrophil gelatinase–associated lipocalin.
