Results of models examining the influence of temporal/demographic factors on variation in pox prevalence.

Values shown are the Z statistics (or χ2 statistics for the smoothed term) and Wald's test P-values for coefficients, along with results of Likelihood ratio tests (LRT) (change in deviance: ΔDev, change in degrees of freedom: Δdf) comparing models with and without the specific term. Factors in bold were retained in the final model.
