Figure 1.

(A–E) Urinary NGAL/creatinine ratio (UNCR) and serum creatinine concentration after gentamicin administration in all 5 dogs. The day of development of acute kidney injury, based on a 7‐fold increase in UNCR and 50% increase in serum creatinine concentration is depicted by arrows. (F) Sequential changes in mean and standard deviation of urinary NGAL/creatinine ratio (UNCR) and serum creatinine concentration after gentamicin administration during induction of acute kidney injury, and during recovery from acute kidney injury. Occasionally, there is an overlap in the standard deviation bars for the UNCR and creatinine lines. Note that each individual standard deviation line arises from the individual dataset that it represents and ends on the small horizontal standard deviation line.
