Trial Outcomes & Findings for Effect of Saxagliptin and Dapagliflozin on Endothelial Progenitor Cell in Patients With Type 2 Diabetes Mellitus (NCT NCT03660683)
NCT ID: NCT03660683
Last Updated: 2023-06-05
Results Overview
Proportion of cells that migrate through SDF1a in a transwell assay. This proportion is represented as a migratory rating scale from 0-1, with 1 being 100% of cells migrate. A larger value indicates better migratory function of the CD34+ cells.

SECONDARY outcome
Timeframe: 16 WeeksAugmentation index was calculated via tonometry with Sphygmocor Device (Pulse Wave Analysis). Augmentation index is calculated as the augmentation pressure (the amplitude of the reflected pulse wave) divided by the pulse pressure (systolic - diastolic) \* 100 to give a percentage of pulse pressure. The software then calculates an estimated Augmentation Index at heart rate of 75 as a form of "normalization." Lower values are generally preferred as they indicate more pliable and healthy arteries.
