Table 6 Multivariable logistic regression of liver fluke and rumen fluke co-infection (dependent variable) across flukicides most commonly used, summer grazing soil scale other livestock present in farm and illness or death due to F. hepatica (independent variables)
| Independent variable | Odds ratio | 95% CI | P-value |
Model (P-value) |
|---|---|---|---|---|
| Flukicides most commonly used | Flukicides most commonly used vs summer soil type vs other livestock present in farm vs illness or death due to liver fluke (P = 0.0458) | |||
| More than one active against more than one stage vs no treatment | 6.74 | 0.75–60.30 | 0.088* | |
| Other livestock present in farm | ||||
| Horses vs none | 4.95 | 0.99–24.62 | 0.051* | |
| Illness or death due to liver fluke in last 5 years | ||||
| Multiple occasions vs rarely | 5.49 | 1.09–27.53 | 0.039 | |
| Multiple occasions vs no | 8.54 | 1.75–41.70 | 0.008 | |
| Multiple occasion vs not known | 9.85 | 1.64–59.22 | 0.012 |
