Fig. 2From: Changes in serum indoxyl sulfate levels after acute myocardial infarction and the correlation with kidney injury: an observational studyRelationship between serum NGAL levels and serum IS levels. a Correlation between serum NGAL levels and serum IS levels. b Serum NGAL levels in patients with high and low IS levels. NGAL, neutrophil gelatinase-associated lipocalin; IS, indoxyl sulfate. *vs. pre-IS < 0.55, P < 0.05. Median IS levels 0.55 μg/mLBack to article page
