Dose effect of glucagon-like peptide 1. Effects of graded doses of GLP-1 and usual insulin before breakfast in volunteers with type 1 diabetes with no endogenous insulin secretion, with number of subjects studied at each dose. Time-averaged incremental (delta) responses (area under the curve divided by total time) of plasma glucose through 3 hours, pancreatic polypeptide(HPP), 0 to 30 min, and glucagon, 0 to 60 min, mean ± se. Polynomial regression analysis (R2) for dose vs incremental responses.
