The results showed no significant association between TNF-α 1031 T/C locus C and CAD susceptibility: the allelic model (C vs. T) (OR:0.973, 95% CI:0.898–1.054); the homozygote model (CC vs. TT) (OR:0.999, 95% CI:0.666–1.498); the dominant model (CC + CT vs. TT) (OR: 0.945, 95% CI:0.860–1.039); regressive model (CCvs.TT+ CT) (OR: 1.020, 95% CI: 0.677–1.539); the heterozygote model (CT vs. TT) (OR: 0.929, 95% CI:0.842–1.025). Here, TNF is linked to coronary artery disorder.
