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 (ESRD), doubling of serum creatinine, progression from microalbuminuria to macroalbuminuria, regression from microalbuminuria to normalbuminuria, cough, headache, hyperkalaemia, and impotence.
MAIN RESULTS
Meta-analysis using a random effects model showed that angiotensin converting enzyme (ACE) inhibitors were more effective than calcium antagonists
