RESUMO
BACKGROUND: This study aimed to evaluate the geographic distribution of United States (US) clinical trial sites utilizedfor guideline changing studies of cholesterol management. METHODS: Randomized trials evaluating pharmacologic interventions for cholesterol treatment and reporting location data (ie, zip code of trial sites) were identified. Location data was abstracted from ClinicalTrials.gov. RESULTS: Half of US counties were over 30 miles from a study site and, social determinants of health were more favorable in counties with versus without clinical trial sites. CONCLUSIONS: Stakeholders such as regulatory bodies andtrial sponsors should incentivize and support infrastructure that would enable a larger number of US counties to be utilized for clinical trial sites. TRIAL REGISTRATION: Not applicable.
