Unmet need for depression treatment before and after the affordable care act.
Article in Social psychiatry and psychiatric epidemiology, 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
purposeThe 2010 Affordable Care Act (ACA) expanded access to depression screening and care. However, changes in unmet need for depression treatment and public mental health equity following ACA implementation remain understudied.
methodsData from 3,522 respondents to the National Health and Nutrition Examination Survey (NHANES) from 2005 to 2020 were used to examine changes in clinically significant depression symptoms that received neither with pharmacologic nor behavioral health treatment. Modified Poisson regression models were used to estimate the association between time period (post-ACA, 2013-2020 vs. pre-ACA, 2005-2010) and unmet need for depression treatment, both overall and stratified by socio-demographic and health care-related variables.
resultsUnmet need for depression treatment decreased from 56% in 2005-10 to 47% in 2013-20, with no significant differences by socio-demographic characteristics. After adjusting for covariates, this corresponded to a 14% reduction in unmet need post- vs. pre-ACA (prevalence ratio (PR) 0.86; CI 0.79,0.95). Only those reporting Medicare vs. another type of insurance coverage experienced a significant decrease in unmet need for depression treatment (PR 0.77; CI 0.60,0.99). A similar decrease in unmet need was observed regardless of having a regular point of care or not, but only detected among those who had used health care services in the prior year (PR 0.80; CI 0.70,0.92) vs. those who had not (PR 1.13; CI 0.92,1.37).
conclusionUnmet need for depression treatment decreased after ACA implementation but remains common. Reductions in barriers to primary care visits and universal screening policies may further decrease unmet need for depression treatment.
