Real-Life Performance of Automated Insulin Delivery Systems for High-Carbohydrate Meals: Are All Systems the Same?

Diabetes Technol TherPublished Crossover study

Authors' conclusion

Results showed no significant differences in glycemic control between meals, suggesting that Margherita pizza can be effectively managed with standard bolus strategies.

Study context

Main finding

As reported in the abstract

  • No significant differences in glycemic control between meals
  • Standard insulin boluses

Further findings

TIR 70-140 mg/dL after pizza, MiniMed 780G vs Control-IQ · 10 h following pizza consumption

Higher time in target range with MiniMed 780G vs Control-IQ

Other glucometrics and insulin delivery

No other significant differences in glucometrics or insulin delivery
