Prediction of the effect on antihyperglycaemic action of sitagliptin by plasma active form glucagon-like peptide-1

Figure 3 Change in insulin and glucagon secretion, high sensitive C reactive protein during three months of sitagliptin administration stratified against plasma active glucagon-like peptide-1 level at baseline. The data is presented as mean and S.D. *statistical significance of change of HbA1c between the high active GLP-1 group and the low or middle groups. GLP-1: Glucagon-like peptide-1; HbA1c: Hemoglobin A1c.
