JAMA. 2008;300(14):1652.

Incorrect Numbers in Text: In the Original Contribution entitled "Lead, Mercury, and Arsenic in US- and Indian-Manufactured Ayurvedic Medicines Sold via the Internet" published in the August 27, 2008, issue of JAMA (2008;300[8]:915-923), 2 numerical errors were published. On page 916 at the bottom of the first column, the power statement should have read that " . . . this sample size provided 90% power to demonstrate a 15% difference in metal prevalence ( = .05)." On page 918 at the top of the second column, the tolerable weekly intake for mercury should have read "5 µg/kg of mercury." These errors do not affect the findings or conclusions of the article.
