Key finding
Transitioning from SMBG to CGM significantly reduced the overall GRI by 9.8 units (95% CI −13.3, −6.3).
This study evaluated the impact of switching from self-monitoring of blood glucose (SMBG) to continuous glucose monitoring (CGM) in adults with Type 1 diabetes, finding significant improvements in glycaemic quality.

Study focus
This study evaluated the impact of switching from self-monitoring of blood glucose (SMBG) to continuous glucose monitoring (CGM) in adults with Type 1 diabetes, finding significant improvements in glycaemic quality.
Improved glycaemic control is crucial for individuals with Type 1 diabetes, as it can reduce the risk of long-term complications such as cardiovascular disease, neuropathy, and retinopathy. The findings support the use of CGM technology as a more effective management tool for diabetes, potentially leading to better health outcomes and quality of life for patients.
The study's sample size may limit generalizability. The duration of the intervention was not specified. Potential biases in self-reported data could affect results.

Transitioning to CGM reduced the overall GRI by 9.8 units (95% CI −13.3, −6.3).
The hypoglycaemia component of GRI decreased by −1.8 (95% CI −2.4, −1.2).
The hyperglycaemia component of GRI decreased by −2.8 (95% CI −5.3, −0.4).
85.4% of participants maintained or improved their GRI zone classification.
