Contrary to our research, Chu et al. [46] presented negative association between circulating PTX3 levels with fasting insulin (r = −0.336, p = 0.012) and homeostasis model assessment of insulin resistance (HOMA-IR) (r = −0.334, p = 0.014) among 57 overweight or obese children. This evidence concerns the gene PTX3 and Insulin resistance.
