Re: “Is the Inverse Association Between Selenium and Bladder Cancer Due to Confounding by Smoking?”

In Table 2 of the article, “Is the Inverse Association Between Selenium and Bladder Cancer Due to Confounding by Smoking?” by Beane Freeman et al. (1), the numbers of cases and controls overall and for never smokers were reversed. The corrected information appears below, and the complete revised table is available at http://aje.oxfordjournals.org.

Table 2.
