Figure 5.

Mean and peak uNGAL concentrations according to presence or absence of sepsis. Shown are box plots of (a) peak urine neutrophil gelatinase-associated lipocalin (uNGAL) concentrations in patients with and without sepsis, by pRIFLEmax strata, and (b) mean uNGAL concentrations in patients with and without sepsis. pRIFLE, pediatric modified Risk, Injury, Failure, Loss, End Stage Kidney Disease; pRIFLEmax, the worst pRIFLE stratum attained; uNGAL, urine neutrophil gelatinase-associated lipocalin.
