The Claim
In patients with type 2 diabetes, red blood cell lifespan is negatively correlated with the hemoglobin glycation index (HGI), with a Pearson correlation coefficient of r = −0.348 (p < 0.01), indicating that shorter red blood cell survival is associated with a greater discrepancy between measured HbA1c and glucose-predicted HbA1c.
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 people with type 2 diabetes, red blood cells don’t live as long when there’s a bigger mismatch between their actual HbA1c levels and what those levels should be based on blood sugar — meaning the body’s sugar coating on blood cells doesn’t always match up with sugar levels.
See the scientific wording
In type 2 diabetes patients, red blood cell lifespan is negatively correlated with hemoglobin glycation index (HGI), with a Pearson correlation coefficient of r = −0.348 (p < 0.01), indicating that shorter RBC survival is associated with greater discrepancy between measured HbA1c and glucose-predicted HbA1c.
What the research says
1 studyThe study found that people with type 2 diabetes who have shorter-lived red blood cells tend to have a bigger gap between their HbA1c test results and what their blood sugar levels would predict, just like the claim says.
