EMVI, Multiple viral infections; ADV gE, antibodies against glycoprotein E of Aujeszky's disease virus; PRRSV, porcine reproductive and respiratory syndrome virus; SIV, swine influenza virus.
W = manifest variables' bootstrapped weights. Only those manifest variables retained in the final path model are shown in Figure 1.
