Figure 3.

Differential effects of GES and WMC findings on recommendations for additional diagnostic testing in suspected gastroparesis are shown. WMC testing promoted less additional test ordering and higher rates of eliminating additional testing (a). Of subjects who were recommended to undergo additional testing, fewer were referred based on WMC alone vs GES alone (b). Of those with elimination of additional testing, more tests were eliminated by WMC alone vs GES alone. More than 50% of additional diagnostic test ordering was recommended based on both abnormal GES and WMC findings. GES, gastric emptying scintigraphy; WMC, wireless motility capsule.
