When investigating the TB group, the unconditional logistic regression analysis showed that 14 SNPs of IL18R1, IL1A, STAT1, LTA, IFNGR1, MBL2, VDR, and IL12RB1 were associated with TB risk under a codominant model (Table S1) and under a dominant and recessive genetic model (Table S2). The gene discussed is IL1A; the disease is tuberculosis.
