Glycemic control and all-cause mortality risk in type 1 diabetes patients: EURODIAB

Target HbA1c below a certain threshold may not be appropriate in this population. We recognize that these low HbA1c levels may be related to anemia, renal insufficiency, infection, or other factors not available in our database. If our data are confirmed, the potential mechanisms underlying this increased mortality risk among those with low HbA1c will need further study (Journal of Clinical Endocrinology & Metabolism)
