C3 plans to hold two working meetings annually, one in the spring and the other in the fall. When feasible, we anticipate having one of these meetings each year in-person. Our meetings are open to clinical experts, patients, methodologists, invited industry partners, and other stakeholders interested in Core Outcome Sets for dermatologic conditions.

The first jointly organized CHORD COUSIN Collaboration (C3) meeting took place on January 28-29, 2022 with over 150 attendees. Our most recent meeting, which took place on October 20-21, 2023, had over 250 attendees. 

Please say tuned for more details about future meetings.
