Results of the generalized linear mixed-effects models (GLMM) and general linear mixed-effects models (LME) of best fit for nematode infection prevalence and mean intensity, respectively, from rabbits sampled in autumn from New Zealand (NZ) and Scotland before and after the arrival of RHDV. All comparisons are made against the intercept of the first level of each factor, i.e. Absent for RHDV and NZ for location. Test statistic (z values) are marked as: ****P < 0.001, **P < 0.05.
