Figure 3.

(a) AUC-ROC using GES as dichotomous variable (delayed or not delayed) was 0.72 (gray line) and 0.77 using GES as a continuous variable (% retention at 4 hour) (red line). (b) AUC-ROC substituting GES for GET through WMC was similar with AUC of 0.7 as dichotomous variable (delayed vs not delayed) and 0.73 as continuous variable. (c) AUC-ROC with a lower threshold of a change in GCSI ≥0.75 was 0.7. AUC-ROC, area under the receiver operator characteristic curve; GCSI, Gastroparesis Cardinal Symptom Index; GES, gastric emptying scintigraphy; GET, gastric emptying time; WMC, wireless motility capsule.
