Patients with chronic kidney disease, including kidney transplant recipients, are at high risk for cardiovascular disease (CVD). In addition to the constellation of traditional CVD risk factors in chronic kidney disease, elevated total homocysteine (tHcy) is notably more prevalent among the general population. The Folic Acid for Vascular Outcome Reduction In Transplantation (FAVORIT) trial is designed to evaluate whether lowering tHcy using vitamin supplementation reduces CVD events in renal transplant recipients.
