ALB and animal viral hepatitis: Binary logistic regression analysis showed that viral hepatitis (OR: 9.468,95% CI: 2.277–39.396), intravenous hormone methylprednisolone usage (OR: 3.560,95% CI: 1.335–9.490), low platelet count (OR: 0.994,95% CI: 0.988–0.999) and albumin level (OR: 0.835,95% CI: 0.767–0.910) were independent risk factors (Table 5).
