Consistently, in a more recent meta-analysis of 40 randomized controlled trials performed in patients with T2DM, compared with standard diabetes therapies (i.e., metformin, sulfonylureas, insulin, DPP-4i, thiazolidinediones) and placebo, GLP-1RA therapy was associated with significant reductions in inflammatory markers such as serum C-reactive protein (CRP) and TNF-α, and a significant increase in adiponectin [80]. This evidence concerns the gene INS and type 2 diabetes mellitus.
