The Claim

In Japanese adults with type 1 diabetes, the cHbA1c model predicts laboratory-measured HbA1c levels with greater accuracy than eHbA1c or GMI, as 92.3% of cHbA1c predictions fall within ±0.5% (±5.5 mmol/mol) of the reference laboratory value, compared to 65.5% for eHbA1c and 73.1% for GMI, indicating superior clinical accuracy.

In plain English

For Japanese adults with type 1 diabetes, a new blood sugar tracking method called cHbA1c is way more accurate than the usual ones — it's really close to the lab test results most of the time.

In Japanese adults with type 1 diabetes, 92.3% of cHbA1c predictions fall within ±0.5% (±5.5 mmol/mol) of laboratory HbA1c, compared to 65.5% for eHbA1c and 73.1% for GMI, indicating that cHbA1c meets a clinically relevant threshold for accuracy more consistently than standard CGM-derived estimates.

  1. Study: Accurate prediction of HbA1c by continuous glucose monitoring using a kinetic model with patient-specific parameters for red blood cell lifespan and glucose uptake

    The study tested a new way to estimate HbA1c from glucose monitor data and found it was much closer to the real blood test than older methods, just like the claim says.
