Maternal and fetal predictors of fetal preservation category. Results of multi-level, partial proportional odds regression model showing the predicted probability of fetuses being viable (VIA; green line), meconium stained (MEC: blue line), decomposed (DEC: red line) or autolyzed (AUT; black line) based on: A levels of interferon alpha (IFNalpha) produced by PRRSV stimulated peripheral blood mononuclear cells (PBMC); the number of B adjacent dead or C adjacent PRRSV positive fetuses; and D the concentration of PRRSV RNA in the maternal fetal interface. The greatest probability of a viable fetus is associated with low viral load in the maternal fetal interface, low interferon alpha levels and no adjacent dead or PRRSV positive fetuses. The greatest probability of an autolyzed fetus is associated with mid-range viral load in the maternal fetal interface, high interferon alpha levels, four adjacent dead fetuses and more than two adjacent PRRSV positive fetuses.
