Arms Assigned Interventions
Experimental: High Dose Multivitamin
Multivitamin with increased folic acid, vitamin B6 and vitamin B12
Drug: High Dose Multivitamin
Vitamin B6 (Pyridoxine HCl): 50 mg Folic acid: 5.0 mg Vitamin B12: 1.0 mg Vitamin B1 (Thiamine HNO3): 1.5 mg Vitamin B2 (Riboflavin): 1.5 mg Vitamin C (Ascorbic Acid): 60 mg d-Biotin: 300 mcg Niacinamide: 20 mg Pantothenic Acid Calcium Pantothenate): 10 mg
Other Name: multivitamin
Active Comparator: Low Dose Multivitamin
Multivitamin devoid of folic acid and with EAR amounts of vitamin B6 and vitamin B12
Device: Low Dose Multivitamin
Vitamin B6 (Pyridoxine HCl): 1.4 mg Folic acid: 0.0 mg Vitamin B12: 2.0 mcg Vitamin B1 (Thiamine HNO3): 1.5 mg Vitamin B2 (Riboflavin): 1.5 mg Vitamin C (Ascorbic Acid): 60 mg d-Biotin: 300 mcg Niacinamide: 20 mg Pantothenic Acid Calcium Pantothenate): 10 mg
Other Name: multivitamin

Detailed Description:
The hypothesis of the trial is as follows: Treatment with a high dose combination of folic acid, vitamin B6, and vitamin B12 will reduce the rate of pooled arteriosclerotic cardiovascular disease outcomes (i.e., pooled occurrence of non-fatal and fatal arteriosclerotic outcomes, including coronary heart, cerebrovascular, and peripheral vascular disease events) relative to treatment with an identical multivitamin containing no folic acid, and Estimated Average Requirement amounts of vitamin B6, vitamin B12, among chronic, stable renal transplant recipients
