In the ACCORD trial, 10,000 patients with type 2 diabetes (mean age, 62; average duration of diabetes, 10 years) were randomized to receive intensive or standard glycemic control; choice of antidiabetic agents was individualized. The main purpose of ACCORD was to determine whether intensive treatment (target glycosylated hemoglobin [HbA1c] level, ≤6%) improved cardiovascular outcomes. The trial was halted after an average follow-up of 3.5 years, when overall and cardiovascular mortality were significantly higher with intensive than with standard treatment (JW Gen Med Jun 6 2008). Now, the researchers present microvascular outcomes.
The principal composite microvascular outcome was end-stage renal disease, rise of serum creatinine to >3.3 mg/…
