MIF and coronary artery disorder: In the Chinese subgroup, a significant association between MIF gene rs755622 G/C polymorphism and CAD was observed under the allelic (OR: 1.207, 95% CI: 1.009–1.443, P = 0.039), recessive (OR: 1.912, 95% CI: 1.160–3.152, P = 0.011), homozygous (OR: 1.971, 95% CI: 1.259–3.086, P = 0.003), and additive (OR: 1.306, 95% CI: 1.030–1.657, P = 0.028) genetic models.
