^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 total number of growth QTL in the genome (after filtering) is 488
^dThe total number of QTL in the genome (i.e. across all QTL types after filtering) is 9892
