We investigated the efficacy of real-time continuous glucose monitoring (rtCGM) and intermittently scanned continuous glucose monitoring (isCGM) on change in A1C. CORRIDA LIFE was a 12 month, real-world, non-randomized trial that assessed the impact of rtCGM (Dexcom G5 or G6) vs. isCGM (FreeStyle Libre 14-Day, Abbott) on A1C and other CGM metrics in adults with T1D. Patients on MDI therapy or CSII with no automatic functions were included. One hundred ninety-one adults with T1D (mean age 40±13 years, A1C 8.1±3.4% [65±14 mmol/mol]) participated in this study; 81 patients initiated rtCGM and 110 initiated isCGM. After 12-months, A1C was significantly lower with rtCGM vs. isCGM (7.1±3.1% [54.1±10.1 mmol/mol] vs. 7.7±3.3% [61.2±12.2 mmol/mol]) , p=0.0001. (Figure 1) The percentage of time in hypoglycemia (<70 mg/dL [<3.9 mmol/L]) was lower among rtCGM vs. isCGM participants (4.3±2.8% vs. 6.4±5.3%) , p=0.003) . Patients with rtCGM spent less time in clinically significant hypoglycemia (<54 mg/dL [<3.0 mmol/L]) (0.9±1.0% vs. 2.3±2.5%, p<0.0001) and more time in target range (70-180 mg/dL [3.9-10 mmol/L]) than isCGM users (67.5±14.8% vs. 57.8±17.0%) , p=0.0002. Use of rtCGM was superior to isCGM in reducing A1C and hypoglycemia and improving other glycemic outcomes.
