I’d like to add an anecdote to confirm the research on the relationship between glycation (A1c) & variability.
My CGM estimated A1c was 5.9-6.0% (eAG 120mg/dL) and my GV is a Standard Deviation of 54mg/dL or 22.5%. Neither loose nor tight control.
My tested A1c was 6.2%, which closely conforms to what the table predicts. A 0.2% higher A1c from the higher variability (although mine is 54mg vs 30, not 100 vs 30)
Would anyone else like to share their tested A1c, 3 month estimated A1c, and SD info? Does your discrepancy between estimated and actual also conform to the table above?
If A1c already accounts for the supposed negative effects of variability, then I wonder if the effects matter beyond what the A1c score already shows.
