aRegions ranked in order of priority based on confidence in predicted probabilities of large (L) or medium (M) between-farm association frequency (CI range ranked from highest to lowest), and small (S) between-farm association frequency (CI range ranked from lowest to highest).

bThe 95% confidence interval range (upper bound - lower bound) for predicted probabilities of large (L), medium (M), and small (S), between-farm association frequencies.
