Trial Outcomes & Findings for Continuous Glucose Monitoring to Measure Effect of Glycemic Index (NCT NCT01145547)

NCT ID: NCT01145547

Last Updated: 2015-10-23

Results Overview

Arterialized blood glucose was monitored at 15 minute intervals and sensed glucose was recorded at five minute intervals. Mean area under the curve was calculated over the 3 hour period after breakfast for both the high and low glycemic breakfast meals.

Measure
Low Glycemic Index, High Glycemic Index
Seven adult subjects with type 1 diabetes participated in two experiments, each consisting of two meals each. In this arm, subjects completed the first study consuming meals with low glycemic index followed by a second study consuming meals with a high glycemic index Dexcom Seven® Plus Continuous Glucose Monitoring sensor: A Dexcom Seven® Plus Continuous Glucose Monitoring sensor was inserted subcutaneously into each subject.
High Glycemic Index, Low Glycemic Index
Seven adult subjects with type 1 diabetes participated in two experiments, each consisting of two meals each. In this arm, subjects completed the first study consuming meals with high glycemic index followed by a second study consuming meals with a low glycemic index Dexcom Seven® Plus Continuous Glucose Monitoring sensor: A Dexcom Seven® Plus Continuous Glucose Monitoring sensor was inserted subcutaneously into each subject.
