It is a huge milestone to have the TRACE database officially closed and to have the final files. Thank you for all of your work with the registry. You were involved in the study even before I came on board in January 2010 and you have been such a valuable partner and resource! There have been innumerable activities, conversations, and messages over these 11+ years. You were always quick with a reply or action and we truly appreciate your guidance and support along the way – especially through two acquisitions and a change in the database platform!
