8 KDOQI Goals in 2014 Evidence that intensive treatment has an effect on loss of glomerular filtration rate (GFR) is sparse* 2.1: We recommend a target HbA1c of 7.0% to prevent or delay progression of the microvascular complications of diabetes, including DKD. (1A) 2.2: We recommend not treating to an HbA1c target of <7.0% in patients at risk of hypoglycemia. (1B) 2.3: We suggest that target HbA1c be extended above 7.0% in individuals with co-morbidities or limited life expectancy and risk of hypoglycemia.
