Response to Comment on Hásková et al. Real-time CGM Is Superior to Flash Glucose Monitoring for Glucose Control in Type 1 Diabetes: The CORRIDA Randomized Controlled Trial. Diabetes Care 2020;43:2744-2750.

The Comparison of CGM in Randomized Study of Real-time and Intermittently Scanned Systems in T1D With Normal Awareness of Hypoglycemia (CORRIDA) study (1) has compared real-time continuous glucose monitoring (rtCGM) and intermittently scanned CGM (isCGM) (also termed flash glucose monitoring) in people with type 1 diabetes (T1D) during a 4-day exercise regimen and over 4 weeks at home. CORRIDA concluded that rtCGM is superior to isCGM in reducing the percentage of time below range (%TBR) and increasing the percentage of time in range (%TIR) in adults with T1D and normal hypoglycemia awareness. We must comment on the glucose sensor–derived conclusions reported.\n\nFirst, all baseline data were collected using the iPro2 rtCGM device (Medtronic), whereas study outcomes used either the Guardian Connect Mobile rtCGM (Medtronic), which like the iPro2 …
