Socioeconomic Disparities in Post-Discharge Suicide Risk Among Individuals With Schizophrenia: A Population-Based Cohort Study in Korea.
Article in Journal of Korean medical science, 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
backgroundThe relationship between socioeconomic status (SES) and suicide in individuals with schizophrenia is complex and not fully understood. This population-based cohort study examined the association between SES and post-discharge suicide risk among individuals with schizophrenia in South Korea.
methodsUsing data from the National Health Insurance Claims Database, as well as national mortality records, this study included 17,565 adults newly hospitalized for schizophrenia between 2017 and 2018. SES was proxied by insurance type-health insurance (HI) versus medical aid (MA). The association between insurance type and suicide risk was examined using Cox's proportional hazards model.
resultsDuring the follow-up period, patients receiving MA-indicating lower SES-had a significantly higher risk of suicide (hazard ratio, 1.135; 95% confidence interval, 1.096-1.175), compared with those with HI, even after adjusting for age, sex, comorbidities, and outpatient follow-up within seven days post-discharge. While early outpatient visits were associated with reduced suicide risk, this effect was notably lower among MA recipients.
conclusionThese findings highlight persistent disparities in suicide outcomes within a universal healthcare system and underscore the need for targeted post-discharge interventions addressing structural barriers faced by socioeconomically disadvantaged individuals with schizophrenia.
