Khan, Sobki, and Alhomida (2015) examined 75 patients to assess the association between fasting blood sugar (FBS) measured iln mmol/l and glycosylated hemoglobin (HbA1c) levels measured as a percentage and reported the following regression equation, which can be used to estimate an HbA1C level from a FBS level. HbA1c = 0.387 (FBS) + 4.855 From this equation you know that in increase of 1 unit in FBS is associated with what change in HbA1c?
