Baseline characteristics of 139 maintenance HD patients in correlation with tertiles of serum NGAL concentrations.

Biochemical analysis was carried out using pre-dialysis serum, unless specified. See S1 Table for other clinical parameters. Values are expressed as mean±SD, median (interquartile range) or number (%). Trend for differences among serum NGAL tertiles was compared by ANOVA for continuous variables and by Kruskal-Wallis test for dichotomous and non-normal variables, respectively. PTH, parathyroid hormone; BUN, blood urea nitrogen; UA, uric acid; CRP, C-reactive protein; TIBC, total iron binding capacity; UIBC, unsaturated iron binding capacity; TSAT, transferrin saturation; CGR, creatinine generation rate; nPCR, normalized protein catabolic rate; Kt/Vsp, single-pool Kt/V.
