Impact of Socioeconomic Status on Functional Outcome After Stroke in Ulaanbaatar, Mongolia.
Article in Journal of the American Heart Association, 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
backgroundStroke disproportionately affects socioeconomically deprived populations, which leads to poor outcomes in disadvantaged groups. This study aimed to assess associations of socioeconomic status (SES) and long- and short-term functional outcome after stroke in Mongolia.
methodsA prospective, population-based incidence stroke study was performed in Ulaanbaatar, Mongolia, between 2019 and 2020. SES indicators were average household family income and highest level of education attainment. The primary outcome was an unfavorable change in functional outcome on the binary modified Rankin Scale (scores 3-6 versus 0-2) measured at 28, 90, and 365 days. Logistic regression was used to analyze the association of SES and outcomes. Generalized linear mixed-effects models were used to assess associations according to repeated measures of modified Rankin Scale over 12 months, and a mediation analysis aimed to determine the mechanism by which SES affects outcome.
resultsA total of 2205 patients (mean age, 58.0±12.8 years; 1330 [60.3%] men) were included. Patients with high-level family income were less likely to have unfavorable short-term (adjusted odds ratio, 0.36 [95% CI, 0.26-0.49]) and long-term (adjusted odds ratio, 0.41 [95% CI, 0.30-0.58]) outcomes. Patients with higher SES experience faster recovery from disability within 1 year, and patients with intracerebral hemorrhage have the slowest recovery rate among the stroke subtypes. Mediation analysis revealed that the impact of SES on functional outcome was mostly direct rather than through other mediators.
conclusionsPatients with higher SES exhibit a better recovery pattern up to 1 year after stroke. SES directly and significantly influenced stroke outcome.
