| Epidemiologicala variable | Odds ratio | 95% CI | Significance level | ||
|---|---|---|---|---|---|
| Type of utilization (dairy, beef or mixed) | 1.3175 | 1.1309 | – | 1.5349 | 0.0004 |
| Animal category | 1.4096 | 1.2505 | 1.5889 | < 0.00001 | |
| Animal purchased in the last 90 days | 2.6009 | 2.0057 | – | 3.3726 | < 0.00001 |
| Use of exogenous oxytocin and sharing of syringe and needle | 18.4205 | 12.3217 | – | 27.5379 | < 0.00001 |
| Sudden impact on daily milk production | 1.0002 | 1.0002 | – | 1.0003 | < 0.00001 |
a
Epidemiological variable with odds ratio >1 (95% CI > 1) is more likely to contain cattle infected with Trypanosoma vivax.
