In an article in the February 2002 issue of Cancer Epidemiology, Biomarkers & Prevention, an author's surname, “Besaratinia,” appeared as “Nia.” For consistency in the literature, the author would like to revise the author list for that article. The corrected citation appears below.

Van Schooten FJ, Besaratinia A, De Flora S, D'Agostini F, Izzotti A, Camoirano A, Balm AJ, Dallinga JW, Bast A, Haenen GR, Van't Veer L, Baas P, Sakai H, Van Zandwijk N. Effects of oral administration of N-acefyl-L-cysteine: a multi-biomarker study in smokers. Cancer Epidemiol Biomarkers Prev 2002;11:167–75.
