Figure 2From: Urine neutrophil gelatinase-associated lipocalin is an early marker of acute kidney injury in critically ill children: a prospective cohort studyMean and peak uNGAL concentrations. Shown are box plots of (a) mean and (b) peak urine neutrophil gelatinase-associated lipocalin (uNGAL) concentrations by pRIFLEmax strata. The mean uNGAL is the mean of uNGAL in each patient's four urine specimens, and peak uNGAL is the highest uNGAL level from each patient. AKI, acute kidney injury; pRIFLE, pediatric modified Risk, Injury, Failure, Loss, End Stage Kidney Disease; pRIFLEmax, the worst pRIFLE stratum attained; R, pRIFLEmax R AKI; I, pRIFLEmax I AKI; F, pRIFLEmax F AKI.Back to article page
