Short Communication: Relationship between Urinary Neutrophil Gelatinase-Associated Lipocalin and Noninfectious Pyuria in Dogs

Table 2

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.
