What Really Matters?: How Insulin Dose, Timing, and Distribution Relate to Meal Composition in Free-Living People with Type 1 Diabetes

Diabetes Technol TherPublished Exploratory observational study

Authors' conclusion

This exploratory study designed to examine the impact of different meal types on insulin dosing requirements in free-living adults with T1D emphasizes the need for individualized adjustment of the CIR depending on meal composition.

Main finding

As reported in the abstract

LGI-LF

5.5

mean · SD 3.4

LGI-HF

mean · SD 3.8

HGI-LF

7.6

mean · SD 5.1

HGI-HF

LGI vs HGI: P = 0.01 · Between LGI-LF and HGI-HF: P = 0.001

Observational data: associations, not effects.

Further findings
