In CAD+T2DM individuals, CTRP9 was positively correlated with insulin, HOMA-IR, TNF-α, IL-6, sE-Selectin, sVCAM-1 and sICAM-1 (p < 0.01) and negatively correlated with adiponectin (p < 0.05); however, a correlation between CTRP9 and IL-6 disappeared after further adjustment for adiponectin. This evidence concerns the gene ADIPOQ and type 2 diabetes mellitus.
