Enhancing the Capabilities of Continuous Glucose Monitoring With a Predictive App
Authors' conclusion
The consistency of the performance of the three predictive models when evaluated on different cohorts of subjects with T1D and T2D on different insulin therapies, including real-world data, offers reassurance for real-world efficacy.
