Overall, inferential analyses revealed a sample of older adults with a rather homogeneous pattern of sociodemographic and clinical characteristics that did not differ significantly between carriers and non-carriers of T2DM, whether the latter were pre-diabetic or not, especially with respect to non-modifiable aspects such as age and sex and non-glycemic general traits such as blood pressure, kidney function, CRP, and TSH levels (Table 1). This evidence concerns the gene CRP and type 2 diabetes mellitus.
