Correlation analysis for methylamine-stimulated hydrogen peroxide release by subcutaneous adipose tissue (ScAT) preparations in function of the HOMA index of insulin resistance. When measured in identical conditions, the oxidation of 1 mM methylamine by homogenates of frozen ScAT released different amounts of hydrogen peroxide depending on the donor. Among the group of twelve obese women depicted in Table 1, these hydrogen peroxide productions were plotted in function of HOMA, an index of insulin resistance. The correlation coefficient r of the linear regression indicated a significant negative relationship at p < 0.02.
