Final global Directed Acyclic Graph (DAG) from additive Bayesian network modelling. The DAG illustrates direct and indirect associations between herd status (positive/negative serology) to at least one of brucella, salmonella or BVD, and farmer interview answers relating to herd biosecurity. A heuristic search with 1000 iterations was run with up to 2 parents allowed. Arcs that were included in at least 50% of local models are shown. Variables with no arcs are not shown. The numbers on the arcs represent the posterior marginal densities; a dashed line indicate negative association. All variables were binomial (no/yes). Variable coding: posbes = herd sero-positive to at least one of the diseases, district1 = Kabarole, district2 = Kamwenge, ncattle25 = herd size 2-5 cattle, careemploy = employees care for cattle, pastshare = share pasture with other cattle herds, boughtcattle = bought or received cattle the last 12 months, equipshare = share equipment with other farms, contothecattle = people from the farm has contact with cattle form other farms, farmhelp = farmers in the area help each other with their cattle
