factory-calibrated sensor for up to 14 days, results demon- strated MARD of 12.2%, with 88.0% of sensor readings within Zone A of Consensus EGA and minimal change in sensor sensitivity over the 14-day wear time.24 Similarly, another study evaluating the feasibility of a factory-calibrated sensor using wired enzyme technology for 5 days demon- strated a MARD of 13.4%, and 83.5% of readings were within Zone A of Consensus EGA.25 Results from those published studies were consistent with the outcomes in the present study. Accuracy of the System was similar across 14 days of sensor FIG. 4. Accuracy of the FreeStyle Libre sensor as a function of various factors or patient characteristics: (A) diabetes type, (B) sex, (C) insertion site, (D) insulin administration (Insulin Ad) (continuous subcutaneous insulin infu- sion [CSII] or multiple daily insulin in- jections [MDI]), (E) body mass index (BMI), (F) hemoglobin A1c (HbA1c), (G) age, and (H) rate of change. Consensus Error Grid zones were Zone A (green), Zone B (blue), and Zone C (red). 6 BAILEY ET AL.
