Compare how often trials restrict a category with county health and environmental-justice data across Massachusetts.
Massachusetts counties
Trials restricting HIV (%)
Color scale from 29.2% (lightest) to 50% (darkest).
Grey counties have fewer than 10 recruiting trials, too few for a fair percentage.
Trials: ClinicalTrials.gov (recruiting, MA sites). Health: CDC PLACES 2023, county crude prevalence. EJ: MassGIS 2020, environmental-justice block groups only. A trial counts in each county where it has a recruiting site; patients travel, so this is a simplification.
Who gets turned away
Pick a county and a person. Each step drops the trials whose eligibility criteria restrict that trait, with the exact sentences that do it.

Criteria alone: cancer type, stage and lab values aren't considered, so this counts trials whose text restricts each trait, not eligibility decisions.
