Fig. 1From: Effect of balanced crystalloids versus saline on urinary biomarkers of acute kidney injury in critically ill adultsUrinary biomarker levels on day 2 by study group. Urinary NGAL and KIM-1 concentration levels scaled to urinary creatinine concentration are displayed for patients in the balanced crystalloid group (green) and saline group (yellow). From top to bottom, the three horizontal lines on each colored box show the upper quartile, median, and lower quartile, and the vertical dashed lines extend to 1.5 times the interquartile range. Each boxplot is overlaid with on dot for each patient’s observed biomarker valuesBack to article page
