Correction

In the article entitled “Reducing Coronary Artery Disease by Decreasing Homocysteine Levels” (February 2003;23:16–30), the units of measure for folate in the last paragraph on page 26 should be micrograms, not milligrams. Therefore, the last sentence on this page should read: “On the basis of these results, Malinow et al estimated that an increase of 350 μg of folate in men and of 280 μg in women per day might prevent 49500 deaths per year due to CAD.”
