Fig 2. Structural equation modelling graph of the direct and indirect effects of risk factors on bTB prevalence (% bTB).

The arrows indicate supported path coefficients. * p< 0.05; ** p< 0.01; *** p< 0.001. Variables are herd size (size), the average herd movement in a day (movement), number of animal transferred (transfer), number of camels (camel), production system (production), and contact with wildlife (wildlife). The proportion of variance explained (R²) appears above every response variable in the model.
