Figure 3From: Effect of glomerular filtration rate impairment on diagnostic performance of neutrophil gelatinase-associated lipocalin and B-type natriuretic peptide as markers of acute cardiac and renal failure in chronic kidney disease patientsPlasma concentrations of the various markers in comparison with an ideal marker of glomerular filtration rate impairment. Patients are clustered in groups according to chronic kidney disease (CKD) stage. Values are scaled on the mean values of CKD patients at stage 1. GFR, glomerular filtration rate; NGAL, neutrophil gelatinase-associated lipocalin; P, plasma; S, serum.Back to article page
