Core outcome set in vitiligo: perspectives from the frontline of research and publishing. What do trialists and editors of five leading dermatology journals really think?

The World Health Organization, in its Guidance for Best Practices for Clinical Trials, recently emphasized the adoption of a core outcome set (COS) to promote standardization and transparency in trial reporting. A core outcome domain set (CODS) is a crucial first step before developing a COS, as it defines the key areas or domains that should be measured. Despite previous attempts, CODS/COS for vitiligo clinical trials are still not widely used. To explore barriers and facilitators to implementing the vitiligo CODS, we conducted two complementary surveys. The first targeted corresponding authors of vitiligo randomized controlled trials and the second survey invited Editors-in-Chief of five leading dermatological journals.
