The table showed the strategy for screening the SNPs. First, 107 SNPs whose P value < E−05 were selected. In these 107 SNPs, the most differentially expressing 5 SNPs were selected, whose p value was less than E−07. 3 SNPs which played key roles in immune regulation or TB and 7 SNPs involved in the interaction network were select
