ADIPOQ and Insulin resistance: About non significant correlation between plasma adiponectin levels and BMI in case group, it should be noted that in the most of previous studies [8,11,25,29] there were significant but weak correlation (r = -0.18 to -0.33) between them, So, in confirming Pliz et al opinion [11], it should be noted that the adiponectin levels may be more associated with blood lipid profile and insulin resistance instead of obesity.
