Error in the Results Section

In the article titled “Association of Testosterone Levels With Anemia in Older Men: A Controlled Clinical Trial”¹ published in the April 2017 issue of JAMA Internal Medicine, there was an error in the data presented in the Results section. Where it previously said “at month 12, 12 of 24 (58.3%) testosterone-treated men with unexplained anemia at baseline were no longer anemic, compared with 6 of 24 (22.2%) placebo-treated men,” the numerator was changed to 14 in the first case, and the denominator to 24 in the second case. This article was corrected online.
