Figure 1From: Evaluation of urinary tissue inhibitor of metalloproteinase-2 in acute kidney injury: a prospective observational studyBiomarker values grouped by acute kidney injury severity. Values of the evaluated biomarkers measured at intensive care unit admission are shown in each acute kidney injury (AKI) severity category (non-AKI (n = 56), stage 1 (n = 15), stage 2 (n = 7), stage 3 (n = 20)). *P < 0.05. Cre, Creatinine; EPO, Erythropoietin; IL-6, Interleukin-6; NAG, N-acetyl-β-d-glucosaminidase; NGAL, Neutrophil gelatinase-associated lipocalin; TIMP-2, Tissue inhibitor of matrix metalloproteinase-2.Back to article page
