In this respect, it was verified that, at baseline, the group without diabetes showed a negative correlation between circulating levels of IL-6 and PMP, which was an unexpected finding since a strongly positive correlation between these molecules has been reported (31, 32), whereas the group with diabetes showed that the circulating IL-10 levels were negatively correlated with PMP and also positively correlated with EMP. This evidence concerns the gene IL6 and diabetes mellitus.
