evidence: In all patients, exogenous GLP-1 infusion reduced the overall glycaemic response during enteral nutrient stimulation (AUC30–270 min GLP-1 (2077 ± 144 mmol/l min) vs placebo (2568 ± 208 mmol/l min); P = 0.02) and the peak blood glucose (GLP-1 (10.1 ± 0.7 mmol/l) vs placebo (12.7 ± 1.0 mmol/l); P < 0.01).
intervention: Exogenous glucagon-like peptide-1 infusion
comparator: Control
outcome: Peak blood glucose
