简要概括
Twenty-one patients with insulin-treated type 2 diabetes with diabetic complications will be recruited to Part 1 of the study, a three-hour combined hyper- and hypoglycaemic clamp, along with a control group of twenty-one individuals with normal glucose tolerance matched for age, gender, and body mass index. Patients with type 2 diabetes will be scheduled for a three-week run-in period with LR and CGM prior to partic...显示更多
