a
Odds ratios (OR) and 95% confidence intervals (CI) are shown for risk factor analyses. Logistic regression was performed to obtain estimates for ORs, which were adjusted for co-variates in the final model.
b
SEOV antibodies were available for 73 rats.
c
Bartonella spp. infection status was available for 26 rats.
NA, not applicable; NS, not significant.
