3. Figure 2
Box plots of biomarker levels in differential diagnosis of acute kidney injury (AKI) and prediction of outcomes. Biomarker levels are presented on a log 10 scale. Boxes indicate median, lower, and upper quartiles. Lower and upper whiskers represent data within 1.5 interquartile ranges of the lower quartile and within 1.5 interquartile ranges of the upper quartile, respectively, of log 10-transformed biomarker levels. Circles represent outliers. NGAL, neutrophil gelatinase-associated lipocalin. *P<0.05, **P<0.01, ***P<0.001.

4. Figure 3
Urinary neutrophil gelatinase-associated lipocalin (NGAL) levels and outcomes. Patients were stratified by NGAL level. Percentages of the subgroups that experience aspects of the composite outcome are shown. P for trend is significant for composite and individual clinical outcomes. RIFLE: Risk, Injury, Failure, Loss of function, End stage renal disease.

5. Figure 4
Sub-stratification of RIFLE severity classes by neutrophil gelatinase-associated lipocalin (NGAL). Patients were stratified by RIFLE severity class (R, I, F) and by NGAL level (cutoff 104μg/l). Percentages of in-hospital mortality, in-hospital dialysis initiation, or a composite outcome are plotted by RIFLE class and NGAL levels. *P<0.05 versus NGAL ≤104μg/l. RIFLE: Risk, Injury, Failure, Loss of function, End stage renal disease.
