Diversity in the context of real-world research refers to the inclusion of individuals from different backgrounds, including but not limited to race, ethnicity, gender, age, sexual orientation, socioeconomic status, and geographic location. It is important to ensure diversity in research because it can provide a more comprehensive understanding of health and healthcare outcomes, as well as enable the development of interventions that are effective for all populations.

In the past, research has often focused on populations that are easier to access, which has led to underrepresentation of certain groups in research studies. This lack of diversity can result in biased and incomplete research findings that do not accurately reflect the experiences and health outcomes of all populations.

Therefore, it is crucial for real-world research to include diverse populations to ensure that research findings can be generalized to all groups. This can help to identify health disparities, understand the root causes of these disparities, and develop interventions that are effective for all populations.

In summary, diversity in real-world research means including individuals from diverse backgrounds to ensure that research findings are inclusive, representative, and generalizable to all populations. By doing so, research can more effectively identify and address health disparities and improve health outcomes for all individuals.
