Figure 5

Total sensitivity indices related to model parameters contributing to output variations. Sensitivity analyses were done for three herd sizes (42, 83, or 125 bred females) and three types of initial virus introduction (3: in weeks 20, 25 and 30; 27/40: on that specific week). Four aggregated outputs over the first five years were analyzed: losses (top left), prevalence in T animals “prevT” (top right), in PI animals “prevP” (bottom left), and in immune dams carrying a PI fetus “prevRP” (bottom right). See Table 1 for definitions and values of the parameters. Parameters slightly accounting for output variance were grouped (in black).
