For the Record Due to a misinterpretation, an article titled "Area Surgeon to Over-see Equine Hospital in N.Y." in the Sept. 13 News Transcript stated that Dr. Patricia Hogan operated on Kentucky Derby winner Barbaro. Hogan did not operate on the horse. She was using Barbaro's surgery, which was performed by another surgeon, as an illustration of how veterinary surgeons now prefer to wait a day before operating after a horse breaks its leg.
