Piona C, Marigliano M, Mozzillo E, et al. - Experts aspired to explore whether 2‐week of continuous glucose monitoring (CGM) data provide a good estimation of long‐term glycemic control and glucose variability (GV) in pediatric patients with type 1 diabetes (T1D) as in adults. Six hundred fifty‐four T1D pediatric patients were selected and 12‐weeks of CGM data, before HbA1c measurement, were obtained. Metrics of glycemic control and GV in incremental sampling periods have been calculated. Four‐week CGM data better illustrates long‐term glycemic control and GV in MDI and isCGM users for T1D pediatric participants. In CSII and rtCGM users, in particular those with good glycometabolic control, the 2-week period may be acceptably precise.
