Community severance and mental health-related hospital visits in New York City.
Article in Environmental epidemiology (Philadelphia, Pa.), 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
Background: Mental health disorders are more prevalent in urban areas; urban living has been linked to increased risk of anxiety, mood, and schizophrenia disorders. These associations may be partially explained by the social and physical urban environment. While traffic-related exposures such as air pollution and noise have been linked to adverse mental health outcomes, the role of road infrastructure and traffic in severing communities and breaking down the social fabric-termed community severance-remains understudied. Methods: We conducted ZIP code-level analyses (2011-2014) to investigate the association between mental health hospital visits and community severance in New York City (NYC), using annual counts of mood-, anxiety-, adjustment-, and schizophrenia-related hospital visits from the New York State Department of Health Statewide Planning and Research Cooperative System database. Community severance was quantified using the community severance index (CSI). We employed generalized additive mixed models to characterize potentially nonlinear associations, adjusting for potential confounders. In secondary analyses, we further adjusted for black carbon to obtain traffic pollution-independent CSI estimates and evaluated potential effect modification by age through stratified analyses. Results: Each interquartile range increase in CSI was associated with higher rates of schizophrenia-related hospital visits (rate ratio [RR] = 1.13, 95% confidence interval [CI] = 1.00, 1.27). Associations for mood (RR = 1.07; 95% CI = 0.98, 1.16), anxiety (RR = 1.06; 95% CI = 0.99, 1.14), and adjustment disorders (RR = 1.07; 95% CI = 0.97, 1.19) were also positive. Results were similar after black carbon adjustment. We found no clear evidence of effect modification by age. Conclusion: Our findings indicate an association between higher levels of community severance and schizophrenia-related hospital visits in urban areas, independent of traffic-related air pollution.
