The Claim

In non-diabetic and non-anemic children, erythrocyte creatine levels do not show a significant correlation with HbA1c levels, with correlation coefficients of R = 0.281 (p = 0.065) in males and R = 0.140 (p = 0.383) in females, indicating that erythrocyte creatine may not reflect glycemic exposure as measured by HbA1c in this population.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

In plain English

In kids who don’t have diabetes or anemia, red blood cell creatine doesn’t seem to track with average blood sugar levels, so it might not be a good way to measure sugar exposure over time.

See the scientific wording

There is no significant correlation between erythrocyte creatine and HbA1c levels in non-diabetic and non-anemic children, with correlation coefficients of R = 0.281 (p = 0.065) in males and R = 0.140 (p = 0.383) in females, suggesting that EC may not reflect glycemic exposure as measured by HbA1c in this population.

What the research says

1 study
  1. Study: Elevation of erythrocyte creatine post-puberty unrelated to erythrocyte lifespan: Implications from the lack of correlation between HbA1c and erythrocyte creatine.

    The study found that in kids without diabetes or anemia, red blood cell creatine doesn’t strongly link to HbA1c, which matches the claim. This means EC might not be a good measure of blood sugar in these children.
