Comparing Guillain-Barré syndrome outcomes between rural and urban hospitals in the United States: A retrospective cohort study.
Article in PloS one, 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
background and purposeRural-urban disparities in neurological care have been well documented, but limited data exist regarding Guillain-Barré Syndrome (GBS). This study examines differences in patient demographics, hospital characteristics, and outcomes among GBS admissions to rural versus urban hospitals in the United States.
methodsUsing the 2021 National Inpatient Sample, we conducted a retrospective cohort study of adult hospitalizations with a principal diagnosis of GBS. Hospitals were classified as rural or urban based on U.S. census designations. Multivariate logistic and linear regression models were used to assess associations between hospital location and outcomes, adjusting for demographic, clinical, and hospital-level factors.
resultsAn estimated 10,035 weighted Guillain-Barré Syndrome hospitalizations were identified, of which 95.8% occurred in urban hospitals. Rural hospitalizations involved older individuals (mean age 56.8 years; 95% CI: 52.5-61.0) compared to urban hospitalizations (51.3 years; 95% CI: 50.3-52.2). Adjusted analyses showed no significant differences in in-hospital mortality (adjusted OR 2.00; 95% CI: 0.11-35.12) or length of stay (mean difference -1.85 days; 95% CI: -6.62 to 2.91). However, total hospital charges were significantly higher in urban hospitals, with an average difference of $39,474 (95% CI: $4,296-$74,651). Discharge disposition was comparable, with 40% of rural hospitalizations and 48.1% of urban hospitalizations discharged home, and 38.8% versus 43.3% discharged to skilled nursing facilities (all p > 0.05).
conclusionsIn this national analysis of over 10,000 Guillain-Barré Syndrome hospitalizations, rural and urban hospitals achieved comparable outcomes in terms of in-hospital mortality, length of stay, complications, and discharge disposition. Rural hospitalizations tended to involve older individuals from lower-income areas, whereas urban hospitals managed more cases with severe comorbidities and generated substantially higher costs. These findings suggest that rural hospitals are capable of delivering effective acute care for GBS, and highlight the need for future research on long-term functional outcomes across geographic settings.
