However, the levels of adiponectin (OR: 1.946; 95% CI: 0.925–4.094; p = 0.079), leptin (OR: 3.723; 95% CI: 0.788–17.583; p = 0.097), TNF‐α (OR: 1.081; 95% CI: 0.911–1.281; p = 0.373), and IL‐6 (OR: 0.878; 95% CI: 0.657–1.173; p = 0.379) were not associated with the risk of T2D. This evidence concerns the gene LEP and type 2 diabetes mellitus.
