METHODS
Data sources:
Medline (1966 to September 2003), EMBASE/Excerpta Medica (1988 to September 2003), Cochrane Central Register of Controlled Trials (2004), reference lists, and authors in the field.
Study selection and assessment:
randomised controlled trials (RCTs) in any language comparing an antihypertensive agent with another antihypertensive agent or placebo in diabetic patients with and without nephropathy. 16 RCTs (n = 8570) in diabetic patients without nephropathy and 43 RCTs (n = 7545) in diabetic patients with nephropathy met the selection criteria. Quality assessment of individual studies was based on allocation concealment, intention to treat analysis, loss to follow up, and blinding.
Outcomes:
onset of microalbuminuria, all cause mortality, end stage renal disease …
