Neighborhood-level social determinants of suicidality in youth with schizophrenia: An EHR-based study.
Article in Schizophrenia research, 2025. 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
backgroundSuicidal thoughts and behaviors (STB) among youth with schizophrenia represent a significant public health concern. It is well-established that neighborhood-level social determinants of health (SDoHs) can impact health outcomes in individuals with schizophrenia. We aimed to investigate the effects of neighborhood-level social determinants on developing future STB in youth with schizophrenia.
methodsWe conducted a retrospective cohort study using electronic health records from the INSIGHT Clinical Research Network, which contains >22 million unique patients across five healthcare systems in New York City. Patients' neighborhood-level SDoHs were measured at their residential ZIP Code Tabulation Area using a composite measure, Social Deprivation Index (SDI), as well as specific components derived from the American Community Survey. Survival analysis was used to study the association between neighborhood-level SDoHs and time to STB since the first schizophrenia diagnosis.
resultsBetween 10/1/2015 and 10/1/2022, we identified 1209 youth aged between 10 and 25 years with a schizophrenia diagnosis and no prior STB, among whom 176 developed STB during follow-up. SDI quintiles were not associated with the risk of future STB, whereas two specific neighborhood characteristics, Gini index and percentage of residents commuting by car/truck/van, were associated with a decreased risk of STB, after controlling for patients' demographic characteristics.
conclusionsAlthough the overall neighborhood deprivation level was not associated with the risk of STB among youth with schizophrenia, specific neighborhood characteristics were. These findings underscore the need for more targeted community-based suicide prevention strategies. Further research is essential to better understand the underlying mechanism of these associations.
