Undisclosed Conflict of Interest

In the Original Contribution entitled “Effect of Vitamin D Supplementation on Recurrent Wheezing in Black Infants Who Were Born Preterm: The D-Wheeze Randomized Clinical Trial,”¹ published in the May 22/29, 2018, issue of JAMA, one of the authors, Kristie Ross, MD, MS, had an undisclosed conflict of interest. She recently discovered that Otsuka Pharma/Pharmavite donated the vitamin D and placebo being used in another trial on which she is a co-investigator, which is funded by the National Heart, Lung, and Blood Institute. Her conflict of interest disclosure should have read: “Dr Ross reported receiving grants and/or nonfinancial support from the National Institutes of Health, ODS, Boehringer Ingelheim, Teva, GlaxoSmithKline, Merck, Flamel, Jazz Pharmaceuticals, and Otsuka Pharma/Pharmavite.” The article has been corrected online.
