1. COVID-19 pandemic is linked with higher undiagnosed diabetes in humans among adults without insurance; non-significant (48.9% pre vs 60.2% post).

   “except among those without insurance where the proportion of undiagnosed diabetes increased non-significantly from 48.9% [35.6-62.3] pre-pandemic to 60.2% [33.3-87.0] post-pandemic.”
