Fig. 3From: Performance of urinary neutrophil gelatinase-associated lipocalin, clusterin, and cystatin C in predicting diabetic kidney disease and diabetic microalbuminuria: a consecutive cohort studyROC of biomarkers for macroalbuminuria diagnosis. The AUC and the cut-off value of each urinary biomarker are presented in the separate table under the figure. aCompared with uNGAL, p < 0.05. AUC, area under the receiver operating characteristic curve; CI, confidence interval; uNGAL, urinary neutrophil gelatinase-associated lipocalin; uCLU, urinary clusterin; uCysC, urinary cystatin CBack to article page
