A meta-analysis was performed with the aim to identify factors with a relevant influence on the expression of clinical
postweaning multisystemic wasting syndrome (PMWS) under experimental conditions. It was found the most successful animal experiment aimed to develop PMWS should include: (1) colostrum-deprived pigs, (2) age of inoculation below 3 weeks, (3) high doses of PCV2 inoculum, (4) PCV2 strain from genotype 1, and (5) co-infection with another swine pathogen as a triggering factor.
