Inclusion criteria were a diagnosis of mild cognitive impairment and participation in one or more AD clinical trials conducted between 2020 and 2024. Demographic information of clinical trial participants was collected via chart review and included self-identified race\/ethnicity, age, residence, and number of clinical trials the patient has participated in. Clinical trial participants were categorized by ZIP codes established by the US Census Bureau. Differences across race\/ethnicity groups were assessed using either Pearson's Chi-squared test or Fisher's exact test.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>A total of 244 patients participated across the state of Hawai\u2018i in 22 AD clinical trials between 2020 and 2024.

White patients had the highest percentage of participation (44%), followed by Asian patients (34%) and NHPI patients (15%).
