Change in urinary biomarker levels from day 0 to day 2 by study group. The change in urinary NGAL and KIM-1 concentration from emergency department presentation to day 2 of hospital admission scaled to urinary creatinine concentration is displayed for patients in the balanced crystalloid group (green) and saline group (yellow), among the 111 patients with urine available at both time points. 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
