Figure 1 Proportion of symptom improvement over time (A) in patients with gastroparesis (diabetics (DM) and idiopathics) and (B) comparing diabetic to idiopathic patients. A test for trend using repeated-measures analysis adjusting for the baseline value of GCSI was computed to analyze whether symptom improvement was significantly different across follow-up, showing significant improvement over time for the gastroparesis group, with the increased improvement occurring in the first 48 weeks (P16-192 weeks = .01, P16-48 weeks=.01, P48-192 weeks = .47; in diabetics: P16-192 weeks = .05, P16-48 weeks = .68, P48-192 weeks = .17; in idiopathics: P16-192 weeks = .04, P16-48 weeks = .001, P48-192 weeks = .39.) P values compare whether the difference in symptom improvement from baseline is statistically significant between the diabetic and idiopathic groups at annual timepoints and also across all timepoints; no differences between the 2 groups occur.
