Dental Care Access for Young Children With Medicaid: Groundtruthing Online Data and Actual Access in the Chicago Metro Area.
Article in Journal of public health dentistry, 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
backgroundMany dental clinics reportedly accept Medicaid for young children per online sources, but parents' experiences suggest that this differs from actual access. Recognizing potential differences between reported and realized access, we studied realized dental care access and neighborhood-level barriers to care in the Chicago metro area.
methodsWe created a list of Medicaid-accepting dental clinics using the Centers for Medicare and Medicaid Services Insurekidsnow.gov "Find a Dentist" search engine tool. Limited to Coordinated Oral Health Promotion Chicago Cohort Study participants' ZIP Codes (N = 51), research staff called each clinic posing as parents trying to schedule their Medicaid-insured children for appointments. Dental clinic and participant addresses were geocoded; using American Community Survey data, we estimated the population's actual access to Medicaid-accepting clinics and neighborhood-level barriers. We used an Enhanced Two-Step Floating Catchment Area analysis to determine realized access and identify disparities.
resultsOf the 379 dental clinics identified online as taking Medicaid insurance for children, only 240 (63.32%) confirmed accepting Medicaid. The catchment area overall met the Health Professional Shortage Area threshold (1 dentist: 5000 population), indicating adequate access for the Medicaid-insured population. Yet, some southern Chicago/southwestern suburbs had exceptionally poor access (< 1 dental clinic: 10,000 population). DISCUSSION: Online data showed many dental clinics accepted Medicaid for children, but our study revealed that realized dental care access varied dramatically, with the fewest clinics in areas with the highest portion of children on Medicaid and the largest socioeconomic barriers. Multilevel change is needed to ensure access to critical dental health services for all.
