By Albert Cai A new study in adolescents and young adults with type 1 diabetes directly compared two automated insulin delivery algorithms. Medtronic’s newer Advanced Hybrid Closed Loop (built into the MiniMed 780G system) improved glucose management more than the MiniMed 670G, though both systems showed impressive increases in Time in Range for this population. Ultimately, the 670G gave users over an hour and a half more time in range each day, while the 780G gave wearers over two hours every day in range! Two Medtronic automated insulin delivery algorithms, the Advanced Hybrid Closed Loop and the MiniMed 670G, were recently compared in a cross-over study, allowing 113 participants to use both algorithms. Results from the study were published in the medical journal
