Figure 1From: Maternal and fetal predictors of fetal viral load and death in third trimester, type 2 porcine reproductive and respiratory syndrome virus infected pregnant gilts 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.Back to article page
