Contributions of intermittently scanned continuous glucose monitoring frequency and bolus insulin dosing on time in range: Analysis of data from continuous glucose monitoring (CGM) and connected insulin pens

Diabetes Obes MetabPublished Retrospective real-world cohort study

Authors' conclusion

While glucose monitoring frequency and insulin bolus dosing are both indicators of engagement with diabetes self-management, higher TIR has a closer association with increased rates of user engagement with isCGM than with increased rates of bolus dosing.

Study context
