Figure 6. The distribution of logged betweenness (n_Infected = 23, n_{Non_Infected} = 324) and degree (n_Infected = 42, n_{Non_Infected} = 1575 scores for all farms (white) as well as the farms which tested positive for HPAI (black).

A Wilcoxon signed rank test revealed that the infected farms are significantly different from infected farms in the network in both betweenness (p<0.001) and degree (p<0.001).
