Table_1_Macrophage migration inhibitory factor gene rs755622 G/C polymorphism and coronary artery disease: A meta-analysis of 8,488 participants.docx

Background and aimsMacrophage migration inhibitory factor (MIF) gene rs755622 G/C polymorphism was suggested to be associated with CAD risk. However, due to the different results among the individual studies, no agreement has been reached till now. Therefore, the meta-analysis on the association of MIF gene rs755622 G/C polymorphism with CAD was performed.Methods and resultsThe association between them was evaluated by calculating the pooled odds ratios (ORs) and the corresponding 95% confidence intervals (CIs). The random-effects models were used because of the significant heterogeneity among them. In this meta-analysis, 8,488 subjects from 9 studies were included. The MIF gene rs755622 G/C polymorphism was significantly associated with CAD under the allelic (OR: 1.213, 95% CI: 1.039–1.417, P = 0.014), recessive (OR: 1.945, 95% CI: 1.214–3.115, P = 0.006), dominant (OR: 0.781, 95% CI: 0.617–0.989, P = 0.041), homozygous (OR: 2.057, 95% CI: 1.289–3.284, P = 0.003), and additive (OR: 1.327, 95% CI: 1.081–1.630, P = 0.007) genetic models.ConclusionMIF gene rs755622 G/C polymorphism was significantly related to CAD, especially in the Chinese population. Persons with the C allele of the MIF gene rs755622 G/C polymorphism might be susceptible to CAD.
