Participants were treated with acotiamide (100\u00a0mg tid) and placebo for 3\u00a0weeks, separated by a 1\u2010week washout period. A daily symptom diary was collected during both treatments. At the end of each treatment period, GE rate and gastric motility were assessed with a <jats:sup>13<\/jats:sup>C\u2010octanoic acid breath test and high\u2010resolution manometry during nutrient infusion, respectively. GI symptom levels were scored during high\u2010resolution manometry. Data were analyzed using mixed models.

However, postprandial antral pressures remained significantly lower compared to placebo (<jats:italic>P<\/jats:italic>\u00a0=\u00a00.015).
