Table 4

Effects of glucagon-like peptide 1 before and after 5-day studies. Effects of vehicle at breakfast and effects of 0.63 μg/kg GLP-1 at breakfast on the day before and on the day after 5-day studies with GLP-1 or with vehicle in paired studies in eight volunteers with type 1 diabetes with no endogenous insulin secretion. Time-averaged incremental values (area under the curve divided by time) (AUC) for plasma glucose through three hours and for plasma pancreatic polypeptide from 0 to 30 min (HPP), mean ± SE, were higher for tests with vehicle at breakfast than for tests with GLP-1 at breakfast, ANOVA, repeated measures, P <.05. Mean AUC values for glucose and HPP did not differ for tests with GLP-1 at breakfast.
