From: Assessing effects from four years of industry-led badger culling in England on the incidence of bovine tuberculosis in cattle, 2013–2017

Figure 3

Adjusted incidence rate ratios (central estimates and 95% confidence intervals) for Officially Tuberculosis Free-Withdrawn (OTF-W) incidence in cattle herds in the buffer zones of intervention areas compared to herds in the buffer zones of comparison areas. Annual incidence rate ratios (IRRs) for Gloucestershire and Somerset compared to comparison areas were estimated in Poisson regression models adjusting for the OTF-W incidence rate in the three years prior to baseline, median herd size, percentage of urban land, the log transformed total number of badgers removed between 1972 and 2006 and the percentage of farms with all land in the buffer zone. Annual IRRs for Dorset compared to comparison areas were estimated in models adjusting for effects in Somerset and Gloucestershire, the OTF-W incidence rate in the three years prior to baseline, median herd size, percentage of urban land, length of motorway, distance between intervention areas and comparison areas and the percentage of farms with all land in the central or buffer zone.
