Outcomes
Primary outcome [1] 322963 0
Rate of gastric emptying as assessed by scintigraphy to oral glucose in non-diabetic Aboriginals compared with non-diabetic Caucasians
Timepoint [1] 322963 0
Gastric emptying data will be recorded in 30second frames for the first 30 minutes (T=0 min to T=30 min), followed by 3 minute frames for the next 210 minutes (T=30 min to T=240 min).
Secondary outcome [1] 380386 0
