In 2006, Qi and colleagues meta‐analysed the association of IL‐6 gene −174G/C polymorphism with T2DM by pooling the results of 10 articles, and they found that the −174GG homozygotes were not significantly associated with the risk of T2DM compared with −174CC genotype or −174GG plus −174GC genotypes,45 in line with the overall findings of the current study. This evidence concerns the gene IL6 and type 2 diabetes mellitus.
