At the start of this study, only one commercial AID system had entered the Austrian market (MiniMed 670G, Medtronic).

The goal is to evaluate and compare the quality of glycemic control of commercially available AID and OS-AID systems and to present all data by an in-depth descriptive analysis of the population.
