The Claim

In non-diabetic and non-anemic females, erythrocyte creatine levels exhibit a positive correlation with age during adolescence (R = 0.557, p < 0.001), whereas no such age-related change is observed in males, indicating a sex-specific post-pubertal increase in erythrocyte creatine that is independent of glycemic markers such as HbA1c.

In plain English

In teenage girls who don’t have diabetes or anemia, red blood cell creatine goes up as they get older, especially after puberty—but this doesn’t happen in boys. This rise isn’t linked to blood sugar levels.

    The study found that red blood cell creatine goes up in teenage girls as they get older, but not in boys, and this isn't related to blood sugar levels—just like the claim says.
