In the Scientific Review and Clinical Applications article entitled
"Vitamins for Chronic Disease Prevention in Adults: Scientific Review," published
in the June 19, 2002, issue of THE JOURNAL (2002;287:3116-3126), the units
for vitamins A, D, K, and B12 and folate in Table 3
should have been micrograms, not micrograms per liter. On page 3119, under
the heading "Vitamin E," "α-Tocopherol is the most abundant form in
foods and is generally the form used in supplements" should have read "γ-Tocopherol
is the most abundant form and α-tocopherol is the form used for most
supplements." On page 3123, under the heading "Vitamin A," "vitamin A is 1500
µg/L" should have read 1500 µg. On page 3124, under the heading
"Vitamin K," "vitamin K is 80 µg/L" should have read 80 µg.
