Inclusive methodological awareness for equity and diversity in biomedical research.

Since publishing its first study, the Special Collection: Inclusive Methodological Awareness for Equity and Diversity has engaged a diverse audience in critically examining the broader question of equity and diversity in healthcare and biomedical research, notably the challenges and opportunities that shape this issue. A common thread that continued to crystallize was that achieving equity and diversity does not necessarily require new or groundbreaking methodologies but, instead, a deliberate, conscientious approach to planning, conducting, evaluating, and reporting research to ensure meaningful representation and a deeper understanding of the population(s) involved. This understanding was echoed in ongoing debates about how ethnic and racial categories are constructed, particularly in how clinical trials and causal inference research engage with these elements to understand and address disparities. It also extends to the discussions surrounding the design and implementation of more inclusive clinical trials, thus emphasizing the importance of recruitment and retention of historically underserved racial and ethnic minorities, as well as other socioeconomically disadvantaged groups. The work described in this collection further highlights the imperative of co-creating complex public health and healthcare interventions in partnership with affected communities. In this editorial, we reflect on these insights and notable recommendations that emerged. Clinical trial number: not applicable.
