Key clinical point: Greater glycemic variability measured as the coefficient of variation for glucose (%CV) level was associated with a higher risk for all-cause mortality in patients with type 2 diabetes (T2D) and a well-controlled glucose status.
Major finding: Compared with patients with a %CV level of ≤20%, those with a %CV level of 20%-25% (adjusted HR [aHR] 1.16; 95% CI 0.78-1.73), 25%-30% (aHR 1.38; 95% CI 0.89-2.15), 30%-35% (aHR 1.33; 95% CI 0.77-2.29), and >35% (aHR 2.26; 95% CI 1.13-4.52) had a higher risk for all-cause mortality.
Study details: This study was a part of the INDIGO study including 1839 patients with T2D who reached continuous glucose monitoring glycemic targets and were classified into five groups by %CV level.
Disclosures: This study was supported by the National Key R&D Program of China, the National Natural Science Foundation of China, and others. The authors declared no conflicts of interest.
