<b>Checking the lack of </b><b>effect of badger culling from 2013 on TB incidence in cattle herds.</b><b> </b><b>Comment on Robertson, A. (2025) preprint, critiquing Langton et al.(2022)</b>.

<p dir="ltr">An analysis based on Defra published data (Langton et al 2022) using a variety of statistical methodologies suggested that badger culling did not affect herd bTB incidence or prevalence over the study period. Langton et al has been critiqued by Robertson 2025, which concludes that there is a significant probability that the analyses will fail to find an effect if one exists. This preprint discusses the two main arguments Robertson has used and presents counterarguments.</p><p><br></p>
