Correction: Reproducibility of Plasma and Urine Biomarkers among Premenopausal and Postmenopausal Women from the Nurses' Health Studies

In this article (Cancer Epidemiol Biomarkers Prev 2010;19:938–46), which was published in the April 2010 issue of Cancer Epidemiology, Biomarkers & Prevention (1), the authors apologize that they have incorrectly stated throughout the article that the fatty acids were measured in plasma. The correct sample type for the fatty acids is red blood cells. The authors state that all values are correct as presented. In addition, the correction of the sample type necessitates a correction to the title of the article. The correct title is as follows: Reproducibility of Plasma, Red Blood Cell, and Urine Biomarkers among Premenopausal and Postmenopausal Women from the Nurses' Health Studies.

To promote the integrity of the scientific literature, the publisher has added a new corrected version of this article. Therefore, the original print version and the new corrected electronic version no longer match. The original article will remain on our web site, although the new version will supersede the original version in electronic searches.
