Binomial mixed effects logistic regression model for the risk factors of testing seropositive for Coxiella burnetii antibodies among dairy cattle farmers. The county is included as a random factor.
| Variable | Total N/n | Prevalence % (95% CI) |
Odds Ratio (95% CI) | p-Value |
|---|---|---|---|---|
| Dairy farmers whose BTM 5 tested C.b. 6 negative | 73/3 | 4.11 (1.41–11.40) | 1.00 | |
| Dairy farmers whose BTM tested C.b. positive | 44/8 | 18.18 (9.51–31.96) | 5.26 (1.31–21.06) | 0.019 |
| Age (years) | 1.00 (0.93–1.07) | 0.989 |
