The roundtable session will take place in several different rooms, organized by theme/topic and/or key health issue. Each presenter sits at a table with a small group of participants to discuss a program or research topic. During the 2-hour session, each presenter will give his/her presentation twice so participants will have the opportunity to attend two roundtable presentations. The session will flow as follows: presenter has 20 minutes to present, followed by a 35-minute question-and-answer period; the participants have the opportunity to change tables and then the process starts over again for the second time. Most presenters are selected from the competitive abstract process.
