Figure 2.
Original recording of intragastric bag volume in a sample subject. The baseline volume tracings denote fundus tone; phasic downward deflections exceeding 30 ml refer to volume waves. Glucagon-like peptide-1(7–36)amide (GLP-1) 0.3 pmol/kg/min (0.3) and 0.9 pmol/kg/min (0.9) dose dependently raised the baseline, representing a reduction in tone, and suppressed volume waves.
