ADIPOQ and type 2 diabetes mellitus: The results revealed that there were statistically significant differences in serum adiponectin levels between patients with both CAD and T2DM and patients with CAD alone (3.80 ± 1.52 μg/ml vs. 5.25 ± 2.35 μg/ml, P = 0.007), between patients with CAD and control subjects (5.25 ± 2.35 vs. 7.04 ± 3.32 μg/ml, P = 0.001), and between patients with CAD + T2DM and control subjects (3.80 ± 1.52 μg/ml vs. 7.04 ± 3.32 μg/ml, P < 0.001), as shown in Table 1.
