Summary of univariable models investigating potential explanatory risk factors for herd‐level prevalence with RBT and C‐ELISA in parallel combination as the outcome variable. P‐value is shown for each explanatory variable followed by the odds ratio (OR) and 95% confidence interval (95% CI) for the OR
