The efficacy of homocysteine-lowering therapy with folic acid to lower homocysteine levels in an effort to reduce cardiovascular disease (CVD) risk in patients with kidney disease remains inconclusive. We conducted a meta-analysis of relevant randomized trials to further examine this issue. ⋯ Our meta-analysis indicates that folic acid supplementation may be effective for CVD prevention in patients with kidney disease, particularly in trials among patients without a history of grain fortification with folic acid, with lower percent baseline diabetes, and in patients with ESRD or ACKD.
