MARD=mean absolute relative difference; YSI=Yellow Springs Instrument.

* FreeStyle Libre users: A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the FreeStyle LibreLink app or when symptoms do not match the app readings.

† FreeStyle Libre 2 users: Finger pricks are required if your glucose readings and alarms do not match symptoms or expectations.

‡ Data from this study were collected with the FreeStyle Libre system. The FreeStyle Libre 2 system has the same features as the FreeStyle Libre system with optional real-time glucose alarms. Therefore, the study data are applicable to both products.

§ Treatment decisions should not be based on real-time sensor glucose readings alone but instead should consider all the information on the results screen.

¶ All values vs. YSI.
