Abstract: Background and Aims: Several treatment modalities are available for type 1 diabetes (T1D), including continuous glucose monitoring (CGM) and flash glucose monitoring (FGM) with MDI, sensor-augmented pumps with predictive low-glucose suspend function (SAP-PLGS) and hybrid closed-loop systems (HCL). The aim of the study was to evaluate the real-world benefits obtained with these treatment modalities.<br />Methods and Results: A cross-sectional study was performed, selecting 4 groups of T1D subjects, regarding their treatment modalities, paired by age, sex and diabetes duration. A comparison was performed, concerning time in different glucose ranges in 2-week sensor downloads. Estimated HbA1c, glycaemic variability measures and sensor use were also compared. 302 T1D people were included (age: 39 ± 12 years, 47% male, diabetes duration: 21 ± 10 years, estimated HbA1c: 7.28 ± 0.84% (56 ± 9 mmol/mol), baseline HbA1c: 7.4 ± 1.0% (57 ± 11 mmol/mol), length of use of the device 8 [3-21] months). Group 1 (CGM + MDI) and 2 (FGM + MDI) showed no differences in time in different glucose ranges. Group 4 (HCL) showed a higher time 70-180 mg/dl and a lower time in hypoglycaemia than group 3 (SAP-PLGS). Group 1 and 2 showed lower time 70-180 mg/dl, higher time in hyperglycaemia and higher glycaemic variability measures than group 3. Group 4 was superior to groups 1 and 2 in all the outcomes.<br />Conclusion: Real-life achievements in glycaemic control and glycaemic variability are described. HCL offer the maximum benefit in terms of time in range and hypoglycaemia protection, compared to CGM + MDI, FGM + MDI and SAP-PLGS.<br />Competing Interests: Declaration of competing interest The authors declare no conflict of interest.<br /> (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.
