Table 5: Comparisons of serum gastrin concentration and frequency and propagation velocity of gastric slow waves before and after treatment as well as between patients with functional dyspepsia and healthy adults.

FGSW: frequency of gastric slow waves; PVGSW: propagation velocity of gastric slow waves.
Note: propagation velocity of gastric slow waves was assessed by the time interval between two consecutive waves that passed through the gastric antrum. “Baseline versus after treatment” refers to patients with functional dyspepsia only.
