Prior incarceration and out-of-pocket dental care expenditures among older adults in the United States.
Article in BMC oral health, 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
backgroundAn accumulating body of research finds that a history of incarceration is associated with poorer oral health and lower dental care utilization. However, no previous research has investigated whether out-of-pocket (OOP) dental care expenditures differ among those with and without a history of incarceration. The purpose of the current study was to examine whether a history of incarceration is associated with OOP dental care expenditures among older adults in the United States.
methodsWe used pooled cross-sectional nationally representative data from the 2012 and 2014 waves of the Health and Retirement Study (HRS), including 11,438 respondents aged 55 and above. A two-part model was employed: a probit model estimated the likelihood of any OOP dental care expenditures among those with and without any lifetime history of incarceration (yes or no), and a generalized linear model (gamma distribution) estimated the relationship between prior incarceration and the amount of expenditure among those with positive costs. Models were adjusted for demographic, socioeconomic, health, and dental-related covariates.
results6.8% of the sample reported a history of incarceration. Prior incarceration was not significantly associated with the likelihood of any OOP dental care expenditures or the amount of OOP dental care expenditures. Supplemental analyses found prior incarceration to be associated with a lower likelihood of any OOP dental care expenditures and a lower amount of dental care expenditures among respondents in the lowest quartile of household income.
conclusionsDespite known disparities in oral health and access, formerly incarcerated older adults do not differ significantly in OOP dental care expenditures compared to never-incarcerated peers on average. Lower OOP dental care expenditures were observed among formerly incarcerated persons at the lowest income quartile. Future research should explore the relationship between prior incarceration and dental care expenditures at other stages of the life course.
