Factors affecting the likelihood of unvaccinated badgers in vaccinate groups testing positive to any of the following diagnostic tests: IGRA (PPDB – PPDA); Stat-Pak; culture.

The proportion of badgers previously vaccinated is modelled as a continuous variable. Badger social group was fitted as a random factor and only significant factors are listed.aOdds ratios are equal to the mean exponent of the coefficient (exp(ß)) and represent change in the odds associated with an individual badger testing positive for M. bovis in relation to the relevant covariate being assessed. Odds ratio z-value); >1 = increased odds (positive z-value).bStandard error of the coefficient.cCoefficient divided by the SE of the coefficient.dThe intercept represents the odds of testing positive for M. bovis for an individual badger in a social group without culture-positive individuals and where no other group members have been vaccinated.eThe number of other previously vaccinated badgers divided by the total number of other badgers caught in a social group at the time that an unvaccinated badger was first caught and tested.
