The results showed no significant association between TNF-α 863C/A locus A and CAD susceptibility: the allelic model (A vs. C) (OR:0.803, 95% CI:0.584–1.103); the homozygote model (AA vs. CC) (OR:0.838, 95% CI:0.612–1.145); the dominant model (AA + CA vs. CC) (OR: 0.793, 95% CI:0.512–1.227); the regressive model (AA vs.CA + CC) (OR:0.828, 95% CI: 0.608–1.129); the heterozygote model (CA vs. CC) (OR: 0.805, 95% CI:0.584–1.103). This evidence concerns the gene TNF and coronary artery disorder.
