GLP1R and type 2 diabetes mellitus: Correlation of Time50% with AUC−15–120 min-glucagon (type 2 diabetes, r = 0.399, p < 0.05; controls, r = 0.471, p < 0.05) and AUC−15–120 min-GLP-1 (type 2 diabetes, r = 0.437, p < 0.05; controls, r = 0.300, p = 0.107) suggests involvement of glucagon and/or GLP-1 in this process.
