^aValues for the different isotypes are mean numbers of ASC per 5 × 10⁵ MNC; for statistical analyses, see the legends to Fig. 3 and 4. 

^bNumber of pigs euthanatized in each group at each time point: PCD 4 and 7 pigs were combined for groups 1 to 5. 

^cNA, not available. 

^dFor an explanation of groups, see Table 1, footnote i.
