Summary of associations between animal health variables and the log enzyme linked immunosorbent assay (ELISA) antibody to Neospora caninum S/P ratio adjusted for the log of antibody titer to bovine viral diarrhea virus (BVDV)^a

Animal health variable	Parameter estimate (95% CI)
Initial sick on arrival treatment	0.10 (−0.66, 0.87) P = 0.79
Initial undifferentiated fever treatment	0.27 (−0.06, 0.61) P = 0.11
Initial no fever treatment	0.42 (−0.19, 1.05) P = 0.18
Initial treatment for gastrointestinal disease	no estimate availableb
Overall chronicity	−0.19 (−1.56, 1.18) P = 0.78
Overall mortality	−0.12 (−1.11, 0.87) P = 0.81

^a Models using N. caninum as a categorical variable and adjustments for presence or absence of antibodies to BVDV at various cutoff values would not converge because of the smaller sample size. Therefore, both antibody levels were considered as log transformed continuous variables

^b Of the 299 cases with data on both BVD and N. caninum antibodies, only 1 was treated for gastrointestinal disease
