Table 5 Logistic regression analyses to determine risk factors for the presence of severe gastric lesions in the pars oesophagea
| Â | Potential risk factor | OR (95% CI) | p-value |
|---|---|---|---|
Simple mixed effects logistic regression model | Finely ground, pelleted feed (vs. meal feed) (Barn included as a random variable with n = 6) | 1.72 (0.64–4.63) | 0.28 |
Final mixed effects logistic regression model | Finely ground, pelleted feed (vs. meal feed) Infectious load of H. suis in fundic gland zone (ln #/mg gastric tissue) Infectious load of F. gastrosuis (ln #/mg gastric tissue) (Barn included as a random variable with n = 6) | 1.71 (0.57–5.13) 1.23 (1.03–1.46) 0.81 (0.68–0.95) | 0.34 0.022 0.0087 |
