Undisclosed Conflicts of Interest

In the Research Letter entitled “Excretion of the herbicide glyphosate in older adults between 1993 and 2016”¹ published in the October 24/31, 2017 issue of JAMA, the conflict of interest statement was incomplete. It should have read: The authors have completed and submitted the ICMJE Form for Disclosure of Potential Conflicts of Interest. Dr Mills reported launching a citizen science crowdfunding site to raise funds for additional research that offers free glyphosate testing with a donation of $130, with tests being run by Health Research Institute (HRI) Laboratories, which processed the samples for the study, and proceeds going to the University of California, San Diego. Dr Fagan reported being founder, chairman of the board, and senior scientist at HRI Laboratories, a 501(c)(3) nonprofit research organization, which is conducting a citizen science research program in which individuals complete a lifestyle and diet survey, provide a urine sample, and partially cover the cost of testing the urine sample for glyphosate ($99/sample). Dr McEvoy reported receiving a grant from the National Institutes of Health. No other disclosures were reported.
