Fig. 3From: Urinary biomarkers predict advanced acute kidney injury after cardiovascular surgeryUrinary biomarker concentrations related to advanced acute kidney injury (AKI). The creatinine-normalized biomarker concentrations were analyzed by unsupervised clustering to determine their relationship to advanced AKI. Full-length view of the cluster diagram has cases orientated along the vertical axis and biomarkers orientated along the horizontal axis. α-GST, α-glutathione S-transferase; π-GST, π-glutathione S-transferase; HJV, hemojuvelin; KIM-1, kidney injury molecule-1; NGAL, neutrophil gelatinase associated lipocalin; UCr, urinary creatinineBack to article page
