Adjusted analysis of the possible factors associated with seropositivity for Neospora caninum in dogs from rural areas in Minas Gerais state, Brazil stratified by rural environments and by dairy farms

Stratum	Associated factors	aOR	95% CI*	P value*
Dairy cattle farms	Dog not fed with commercial feed (n = 95)	2·110	1·004–4·484	0·051
	Dog that spontaneously hunts (n = 16)	4·449	1·420–13·943	0·010
All rural properties (dairy cattle, beef cattle, coffee planting farms)	Dairy cattle farming (n = 207)	3·471	0·999–12·051	0·050
	Dog used as guard dog (n = 159)	3·385	1·168–4·871	0·017
	Dog that spontaneously hunts (n = 29)	5·807	1·987–16·975	0·001

aOR, Adjusted odds ratio; CI, confidence interval.

Goodness-of-fit (dairy cattle farms): χ² = 0·563, P = 0·905.

Goodness-of-fit (all rural properties): χ² = 2·972, P = 0·396.

^*Multivariate logistic regression.

Variables evaluated in the model (P>0·05): ‘possibility of contact with/ingestion of aborted fetuses/placenta’, ‘beef cattle farm’, ‘use of dog as a companion’, ‘dog used as guard dog’.
