The latter result is in accordance with the findings by Monnier et al.9 who suggested that the relative contribution of PPG decreased, whereas the relative contribution of fasting glucose increased, from the lowest to the highest HbA1c quintile among non-insulin-treated T2D patients with HbA1c ranging from ~6 to 12% (42–108 mmol/mol). This evidence concerns the gene INS and type 2 diabetes mellitus.
