Correlation between urinary variables and uNGAL concentration on 33 healthy dogs.

Variable	Sample	Median (IQR)	Spearman's coefficient (rho)**
	UPC	0.04 (0.02–0.16)	rho = 0.572  P = 0.0014
	WBCs	2 (0–10)	rho = 0.561  P = 0.0015
uNGAL	Epithelial cells*	0.75 ± 1*	rho = 0.205  P = 0.2529
	Crystals	0 (0-1)	rho = 0.101  P = 0.5752
	Casts	0 (0–2)	rho = 0.187  P = 0.2964

^*Mean ± standard deviation.

^**rho: nonparametric measure of the strength and direction of association between two variables.

IQR: interquartile range.

P < 0.005 is considered significant.
