Top-ranked Akaike Information Criterion (AIC) models with parameter values for domestic poultry and wild bird H5N1 outbreaks on the Qinghai-Tibet Plateau.

aA priori analysis of poultry outbreaks and BHGO UD indicated BHGO exposure to H5N1 sources on the wintering grounds; Single variable a priori poultry model: BHGO UD (p = 0.032).bParameters for poultry models included bar-headed goose utilization distribution (BHGO UD), poultry density (PD), latitude (Lat), and cropland (Crop). Parameters for wild bird models include BHGO UD, PD, Lat, grassland, and wetlands (Wetl).wi = Akaike weights, β = model coefficients, SE = standard error (SE), Pr(>|z|) = significance value, Pr(>|×2|) = Chi-square goodness of fit test.
