Final multivariate logistic regression for risk factor to Neospora caninum infection in dogs from Minas Gerais, Brazil (P⩽0·05)

Factors	OR	95% CI	P
Dog used as guard dog (n = 186)	2·840	1·181–6·831	0·020
Dog that spontaneously hunts (n = 30)	4·436	1·239–15·873	0·022
History of bovine abortion (n = 78)	3·301	1·462–7·456	0·004
Dog aged >4 years (n = 204)	2·820	1·256–6·332	0·012

OR, Odds ratio; CI, confidence interval.

Goodness-of-fit: χ² = 3·498, P = 0·624.

Variables tested in the model (P ⩾ 0·05): ‘fed on commercial feed’, ‘use of dog as a companion’, ‘possibility of contact with/ingestion of aborted fetuses/placenta’, ‘dairy farm’, ‘beef cattle farm’.
