The incretin hormones and glucagon. Geometric mean plasma GLP-1 (a), geometric mean plasma GIP (c) and geometric mean plasma glucagon (e) measured 0, 20, 40, 60, 120 and 180 minutes after glucose ingestion, all with 95 % confidence intervals (CIs). Geometric mean iAUC of plasma GLP-1 (b), geometric mean iAUC of plasma GIP (d) and geometric mean iAUC of plasma glucagon (f) (with 95 % CI). *Significant difference between OGTT and IVGI; #significant difference between groups. GIP glucose-dependent insulinotropic peptide, GLP glucagon-like peptide, iAUC incremental area under the curve, IVGI intravenous glucose infusion, OGTT oral glucose tolerance test
