A higher Kullback–Leibler (KL) value indicates more divergence of the root state posterior probability from its prior [13]. Also shown is the Association Index (AI) and the Parsimony Score (PS) from BaTS. For AI and PS, statistical significance indicates the diffusion is structured by geography [49]. Both HA and NA had an AI and PS p-value < 0.05.
^*p-value < 0.05.
