Additional file 7: of 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 and fetal level factors associated with fetal preservation category in type 2 PRRSV inoculated third trimester pregnant gilts. Variables included in the unconditional, full and final partial proportional odds models to investigate factors associated with fetal preservation category are listed; factors were measured at the gilt or fetal level; only factors significantly associated with the odds of fetal death or PRRS viral load in fetal thymus were included.
