Figure 2From: The plasma level and biomarker value of neutrophil gelatinase-associated lipocalin in critically ill patients with acute kidney injury are not affected by continuous venovenous hemofiltration and anticoagulation appliedMass removal rate, mass adsorption rate, sieving coefficient, and clearance of NGAL during CVVH over time (median and interquartile range). Symbols: ● no anticoagulation, ■ heparin, ▲citrate. Total mass-removal rate and mass-adsorption rate were similar across groups and did not change over time. Sieving coefficient and clearance decreased over time in all groups (P < 0.001).Back to article page
