and 15Á5% reporting, respectively. However, our results show persistent under-representation of patients with skin of colour. Limitations of the study include incomplete race/ethnicity reporting, which may misrepresent certain groups. Race is also currently broadly categorized (white, black etc.). While individuals within the same racial groups share phenotypic and genetic characteristics, variations exist within racial subgroups (e.g. South Asian, East Asian). As globalization continues, evolving definitions of race and ethnicity are needed. Bhattacharya and Silverberg found potential differences in the efficacy of nonbiologic systemic AD treatments based on racial or ethnic subgroups. 8 With over 25 pipeline AD medications under investigation, 3 AD treatments provide a unique window for identifying gaps to improve future RCTs. Low representation of patients with skin of colour in clinical trials limits the generalizability of trial outcomes. Including trial sites within diverse areas, promoting awareness to patients with skin of colour, standardizing race/ethnicity classifications, and including race/ethnicity subanalysis can all help to encompass global racial and ethnic heterogeneity better. While progress has been made to diversify AD trials, our results highlight continued under-representation of patients with skin of colour. By encouraging transparent reporting of race and ethnicity data, practitioners may provide more individualized patient care and improve patient outcomes.
