Associations between haemoglobin A1c and mortality rate in the KORA S4 and the Heinz Nixdorf Recall population‐based cohort studies

There is limited knowledge about mortality risk in persons with increased haemoglobin A1c (HbA1c) levels below the diabetes threshold. Moreover, little is known about how associations between increased HbA1c and mortality depend on the length of follow‐up. Therefore, we studied associations between HbA1c and mortality over long‐term follow‐up in persons with and without known diabetes.
