Key clinical point: In patients with type 2 diabetes (T2D), increased visit-to-visit variability in glycated hemoglobin (A1c) and fasting plasma glucose (FPG) was associated with a higher risk for severe hypoglycemia; however, FPG variability better predicted severe hypoglycemic events than A1c variability.
Major finding: Each standard deviation (SD) increase in the variability in A1c and FPG significantly increased the risk for hypoglycemia requiring any third-party assistance (adjusted hazard ratio [aHR] 1.10 and aHR 1.40, respectively; both P < .01) and hypoglycemia requiring medical assistance (aHR 1.11 and aHR 1.46, respectively; both P < .01). However, FPG variability better predicted severe hypoglycemic events than A1c variability (P < .01).
Study details: Findings are from a post hoc analysis of the ACCORD trial including patients with T2D and a high risk for cardiovascular disease, of which 10,052 and 10,068 patients were included in A1c and FPG variability analyses, respectively.
