Authors may add co-authors to a previously submitted abstract any time prior to the Nov. 30 submission deadline by logging into the DDW abstract submission site. To edit an abstract, return it to draft status, save your changes to the author string, and then resubmit. Please note that your abstract must be resubmitted prior to the 21:00 Eastern time (UTC –5) deadline on Nov. 30 or it will not be considered for presentation at the meeting.  

No edits to author strings, author names, or author institutions will be accepted after the Nov. 30 deadline.
