The Randomized Olmesartan and Diabetes Microalbuminuria Prevention (ROADMAP) trial • Randomized, double-blind, multicenter, controlled trial. • 4447 patients with type 2 diabetes and at least one additional cardiovascular risk factor, but with no evidence of renal dysfunction • Olmesartan (at a dose of 40 mg once daily) versus placebo for median 3.2 years • Other antihypertensive drugs (except ACE inhibitors and ARBs) were used as required for BP control (<130/80 mm Hg). • The primary outcome was the time to the first onset of microalbuminuria 1.Haller H, et al.
