Excerpt

To the Editor: Dr Jenkins and colleagues raise two issues. The first relates to the validity of the strong inverse relationship between disposition indices and plasma glucose concentrations. The second relates to the effects of obesity on indices of beta cell function. They state that our conclusion appears inconsistent with their finding that “baseline adiposity predicts reduced beta cell function at 6-year follow up, and does so independently of diabetes risk status.” They also state that our findings “are based on spurious correlations.” We offer the following comments. …

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
