Otherwise, the PPARG allele C was not significantly associated with the marker of glycaemia, insulin resistance or insulin sensitivity, both overall and by type 2 diabetes status; with evidence however that the effect on 2-hour glucose if any, could be more pronounced in people with type 2 diabetes (p-value = 0.002 for the PPARG allele C type 2 diabetes interaction). This evidence concerns the gene PPARG and Insulin resistance.
