STUDY QUESTION

Setting:

77 centres in the USA and Canada.

Patients:

10 251 patients 40–79 years of age (mean age 62 y, 61% men) who had type 2 diabetes, glycated haemoglobin concentration >=7.5%, and cardiovascular disease or, if >=55 years of age, risk factors for cardiovascular disease. Exclusion criteria included body mass index >45 kg/m2, serum creatinine concentration >132 mmol/l (1.5 mg/dl), and frequent or recent serious hypoglycaemia.

Intervention:

intensive glucose control to achieve a target glycated haemoglobin concentration <6.0% (n = 5128) or standard glucose control to achieve a target glycated haemoglobin concentration of 7.0–7.9% (n = 5123).

Outcomes:

composite of cardiovascular events (non-fatal myocardial infarction or stroke, or death from cardiovascular causes). Secondary outcomes included death from . . . [Full text of this article]
