In this article (Cancer Epidemiol Biomarkers Prev 2010;19:1185–92), which was published in the May 2010 issue of Cancer Epidemiology, Biomarkers & Prevention (1), the authors apologize for an error in which standard curve values from a previous study were accidentally and inappropriately applied to the present one. Therefore, some of the values in Table 1 are incorrect. The corrected Table 1 is shown below, with revised values for HBMA, MHBMA, HEMA, and summed mercapturic acids. The statistical analysis and conclusions of the article are unchanged.
Geometric means of biomarker levels in women who did frequent home cooking (daily cooks) versus women randomly selected from the Singapore Chinese Health Study (random controls)

NOTE: Adjusted for age at sample collection. The urinary biomarkers and leukocyte DNA biomarkers were obtained from different groups of daily cooks but the random controls were the same for both (see Materials and Methods).
aThe sum of HPMA, HBMA, SPMA, MHBMA, and HEMA.
bThree samples could not be analyzed because of technical problems.
