Figure 1

Gilt level predictors, measured before inoculation, associated with the fetal mortality rate. Grey font (text box at bottom right) indicates variables that were included in the full model (P < 0.1 in unconditional analyses), but were excluded from final models due to non-significance during stepwise backwards elimination. Levels of IFNα in supernatants of PRRSV stimulated PBMC (IFNα_sup_PRRSV; pg/mL) were positively associated (red arrow) with fetal mortality rate, whereas both IL10 in serum (IL10_serum; pg/mL) and absolute numbers of NK cells (cells × 109/L) were negatively associated (green arrows) with fetal mortality rate. P-values and coefficients (β) are indicated for significant factors.
