Participants were required to wear a Dexcom G7 (Dexcom), FreeStyle Libre 3 (Abbott), and Simplera (Medtronic) rtCGM simultaneously. From 8:00\u2009AM (initial measurement) to 10:00\u2009PM (final measurement), duplicate capillary blood glucose measurements were taken at 2\u2010h intervals using the Contour Next One glucometer (Ascensia Diabetes Care) and recorded in addition to the actual displayed sensor glucose values. The performance of the rtCGM systems was evaluated by means of median absolute relative difference (MedARD) and interquartile range [IQR] against the reference blood glucose. Absolute relative differences (|ARD|) of the three rtCGMs were analysed using the Kruskal\u2013Wallis test (\n p<\/jats:italic>\n \u2009<\u20090.05).\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Overall, the MedARD [IQR] for Dexcom G7 was 8.4% [3.6\u201314.0] (723 comparison points), for Libre 3 7.5% [3.1\u201313.4] (723 comparison points), and Simplera 13.8% [6.9\u201322.5] (719 comparison points). No significant differences were found between Libre 3 versus Dexcom G7 (\n p<\/jats:italic>\n \u2009=\u20090.35). A significant difference was found for Dexcom G7 versus Simplera and Libre 3 versus Simplera (\n p<\/jats:italic>\n \u2009<\u20090.0001).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n
