Table 4. Odds Ratios and 95% credible intervals (in parentheses)–relative to a baseline of survey-only core areas–for recurrence in the different treatment areas in the periods during and after the culling; adjusted for herd size, number of reactors, and breakdown history in the previous three years.

Models are fitted to each follow-up period (12, 24 and 36 months) separately. Results are further stratified into core and buffer zones.
