High poverty and digital divide correlate with clinical trial deserts

A significant portion of the U.S. population, approximately 40 million adults, resides in clinical trial (CT) deserts for gastrointestinal cancers, indicating a major accessibility issue. Areas identified as CT deserts are notably associated with higher area deprivation and digital divide indices. Multivariable analysis revealed that regions with elevated deprivation and digital divide scores had over double the odds of being designated CT deserts compared to more affluent areas. This data underscores the urgent need for equitable clinical trial access.
