The interaction analysis of the two SNPs (rs3806933 in TSLP and rs7025417 in IL33) indicated significant associations with a P value of 3.67 × 10−4 for the type of rs3806933_TT/rs7025417_TT, which provided a nearly threefold increase in the risk of CAD (OR = 2.98, 95%CI: 1.63–5.43; Table 4; Figure 4). This evidence concerns the gene TSLP and coronary artery disorder.
