real-time continuous glucose monitoring (rtCGM) has become a key component of intensive insulin regimen treatment and is considered the standard of care for patients with type 1 diabetes (T1DM). There have been few long-term studies to evaluate the efficacy of rtCGM and various insulin injection methods in the past. The research group previously reported the results of the COMISAIR study, which is a 1-year, non-randomized, real-world study that evaluates the long-term use of sensor-augmented insulin regimens (SAIR). In the current 3-year follow-up study, investigators investigated the effects of SAIR interventions on glycemic control and treatment persistence in a larger cohort, aiming to provide further supporting evidence for the use of rtCGM in the management of T1DM.
