In the news story, "NIH opens conflict-of-interest investigation" (Nature Med., 5, 129; 1999) we incorrectly reported that Richard Eastman, a researcher at the National Institute of Diabetes and Digestive and Kidney Diseases, has received consulting fees totaling $784,500 from the pharmaceutical company, Warner-Lambert. The correct amount is $78,455 over the three-year period indicated. We regret this error.
