To the Editor In a recent article published in JAMA Surgery,1 a related pilot study and publication in the Journal of Plastic Surgery and Hand Surgery2 should have been discussed and referenced. This pilot study included a preliminary analysis of 19 276 plastic surgery patients from the American College of Surgeons National Surgical Quality Improvement Program (NSQIP) from 2005 to 2011. After this study was accepted and published in the Journal of Plastic Surgery and Hand Surgery, we published a second large study in JAMA Surgery assessing the effect of surgical duration on venous thromboembolism that included a larger set of patients (ie, 1 432 855 patients who had undergone all types of surgery) from the NSQIP database. I would like to apologize to the editorial board and the JAMA Surgery readership for not properly referencing the pilot study; not doing so was an oversight that did not follow the JAMA Network requirements.
