Sensitivity analysis in which glucagon values <25 ng/mL were replaced with 25 ng/mL showed similar results (inhibition of glucagon secretion by hyperglycemia 0.85-fold [95% CI: 0.79–0.92] and by GLP-1 0.96-fold [95% CI: 0.92–0.997] in all subjects). This evidence concerns the gene GCG and Hyperglycemia.
