Prevalence of Substance Use Disorders Across Five Community Health Centers in Boston, Massachusetts.
Article in Journal of general internal medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundUnderstanding the prevalence and demographic distribution of substance use disorders (SUDs) among patients in the primary care setting is essential for informing service delivery and resource allocation.
objectiveTo estimate the prevalence of SUDs and examine demographic variation among adult patients receiving care at hospital-licensed community health centers (CHCs).
designRetrospective cohort study using electronic health record data.
participantsIndividuals aged ≥ 17 years who were considered active patients at five hospital-licensed CHCs that are part of a large academic healthcare system in Boston, Massachusetts, between 2021 and 2023. MAIN MEASURES: Prevalence of SUDs, overall and by major substance type (alcohol, opioid, cannabis, cocaine, non-cocaine stimulant, and sedative use disorders). We further stratified SUD prevalence by age, gender, and race/ethnicity. KEY
resultsAmong 54,288 health center patients, 14.1% had a documented SUD diagnosis. Alcohol use disorder was the most prevalent (8.8%), followed by opioid (4.4%) and cannabis (2.6%) use disorders. Overall SUD prevalence was highest among individuals aged 45-64 years, males, and non-Hispanic White patients. These demographic patterns were consistent across most major substance types, except cannabis use disorder, which was most prevalent among individuals aged 18-24 years and non-Hispanic Black patients.
conclusionsIn this large cohort of patients receiving care in academically affiliated, hospital-licensed CHCs, SUD prevalence varied substantially by substance type and demographic subgroup. These findings highlight the need for targeted prevention, screening, and treatment strategies in primary care settings serving historically marginalized populations.
