^aEffect: The effect of SNP across groups vaccinated, or not, for PRRS (main) or the effect of SNP interacting with PRRS vaccination status (interaction)
^bSNP List: Lists of SNPs from the GWAS with a –log₁₀ p-value above 2, 2.5 or 3
^cThe number of unique SNPs mapping to health QTL in the genome is 14,063
^dThe total number of SNPs used for the GWAS was 61,729
