Higher CGM time below range—especially TBR <70 mg/dL—and greater glucose variability are linked to increased severe hypoglycemia risk in 1,550 people with type 1 diabetes.
- Why it matters: HbA1c alone may not capture hypoglycemia risk or glycemic instability, leaving clinicians without CGM-based predictors for severe events in type 1 diabetes.
- What they did: Pooled individual-level data from 10 type 1 diabetes studies; derived CGM metrics over a 14-day baseline and used Cox regression to test associations with severe hypoglycemia and DKA, with and without HbA1c adjustment.
- The result: Over median 16 weeks, 65 severe hypoglycemia events occurred; TBR <70 mg/dL showed an HbA1c-independent association (HR 1.52 [1.29–1.79] per 1-SD higher), supporting CGM metrics for hypoglycemia risk assessment beyond HbA1c.
