Figure Lengend Snippet: Study timeline. The schematic illustrates the study timeline, including retrospective and prospective data collection periods surrounding the transition from Dexcom G6 ® to Dexcom G7 ® (Day 0). Retrospective data collection: CGM data were retrieved at three time points before the transition (−90, −30, and −14 days), concluding the day before switching to Dexcom G7. Prospective data collection: at three time points after the transition (+14, +30, and +90 days), incorporating the day of the G7 transition in the analysis. Participants underwent two key study visits: Baseline Visit (Day 0): Included baseline questionnaires, anthropometric measurements, and HbA 1c assessment. Final Visit (+90 days): Included final questionnaires, anthropometric measurements, and HbA 1c assessment. *The day of the G7 transition is included in the prospective data downloads (+14, +30, +90). Retrospective data collection (−90, −30, −14) concludes the day before transitioning to G7. CGM, continuous glucose monitors.

Article Snippet: The study recruited individuals with T1D from diabetes care centers who met the following inclusion criteria: (i) Diagnosis of T1D; (ii) Age ⩾18 years; (iii) Current use of the Tandem t:Slim X2 insulin pump with Control-IQ; (iv) Prior use of the Dexcom G6 CGM system for at least 3 months before study enrollment; (v) Willingness to transition to the Dexcom G7 system; (vi) Ability to provide informed consent and comply with study procedures; (vii) Adequate use of the system and adherence to the Control-IQ automatic mode.
