Impact of continuous glucose monitoring on glycaemic risk index in adults with type 1 diabetes using multiple daily insulin injections in the GOLD trial

Switching from SMBG to CGM significantly improved GRI in adults with T1D on MDI therapy. Compared with TIR, GRI demonstrated greater responsiveness to treatment-related changes. As a composite metric that integrates both hypo- and hyperglycaemia, GRI may serve as a valuable endpoint for evaluating interventions and as a complementary measure in clinical practice.
