Finally, results of multiple linear regression analysis in patients with T2DM (T2DM and CAD+T2DM groups) revealed the independent association of CTRP9 with BMI (β [SE] = 2.76 [1.17]; p = 0.021), HOMA-IR(β [SE] = 61.71 [20.54]; p = 0.003), sE-Selectin (β [SE] = 0.737 [0.34]; p = 0.033) and sVCAM-1(β [SE] = 0.084 [0.04]; p = 0.041). The gene discussed is C1QTNF9; the disease is type 2 diabetes mellitus.
