Comparative Performance Analysis of Manual and Updated Optional Calibration Algorithms for a Continuous Glucose Monitoring System
Authors' conclusion
Both algorithms of CSAir demonstrated robust performance and reliability with improved accuracy with the updated version. The study results of the CSAir suggest its suitability for nonadjunctive use.
