Our History
C3 represents a union between two established outcomes research groups: Consortium for Harmonizing Outcomes Research in Dermatology (CHORD) and the Cochrane Skin Core Outcome Set Initiative (CS-COUSIN).
We are a global research organization focused on supporting the development, dissemination, and implementation of high-quality Core Outcome Sets for trials and practice in dermatology and related areas, through the engagement of patients, clinical experts, methodologists, and industry partners.
