Electrogastrography associated with symptomatic changes after prokinetic drug treatment for functional dyspepsia

Figure 1 Proportion of gastric slow waves on electrogastrography. A: Pre-prandial; B: Post-prandial. ^aP < 0.05 vs pre-treatment.

Figure 2 Changes in dominant frequency and dominant power, dominant frequency instability coefficient and dominant power instability coefficient after prokinetic treatment. A: Dominant frequency (DF) in pre-prandial electrogastrography (EGG); B: DF in post-prandial EGG; C: Dominant power (DP) in pre-prandial EGG; D: DP in post-prandial EGG; E: Dominant frequency instability coefficient (DFIC) in pre-prandial EGG; F: DFIC in post-prandial EGG; G: Dominant power instability coefficient (DPIC) in pre-prandial EGG; H: DPIC in post-prandial EGG. ^aP < 0.05 vs pre-treatment.

Figure 3 Power ratio before and after the 8-wk course of treatment. ^aP < 0.05 vs pre-treatment.
