Patent foramen ovale diagnosis in young stroke patients: analysis of recurrence and mortality.
Article in Journal of neurology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundRevised European Stroke Organization guidelines in 2018 recommend early patent foramen ovale (PFO) detection and closure in patients aged 60 or younger who suffered an ischemic stroke. Our primary aim was to analyze the impact of these guidelines on the detection of PFO. Our secondary endpoints were to investigate the differences in the risk of recurrence and mortality among PFO status.
methodsWe conducted a population-based, retrospective cohort study in Catalonia using linked health administration databases. We included all ischemic stroke patients aged 18-60 from 2016 to 2021, collecting PFO diagnosis, demographics, comorbidities, stroke recurrence, and mortality.
resultsA total of 13,780 individuals suffered an ischemic stroke, representing a raw annual incidence rate of 30.3 cases-per-100,000 inhabitants/year. PFO was detected in 749(5.4%), and these were younger, and had a lower prevalence of risk factors than patients without PFO (all p value < 0.05). After adjusting for age and sex, PFO diagnoses increased by 59% following the guidelines update. Five-year recurrence was 12.1% [95%CI 11.3-12.9] with no differences by age and PFO. Socioeconomical status and diabetes emerged as predictors of recurrence. Stroke patients with PFO showed a lower mortality rate (p value = 0.016). However, when stratified by age, PFO was linked to lower 4-year mortality only in patients ≤ 50 years.
conclusionsWe confirm a greater detection of PFO in real-world practice following the update of guidelines. Regarding the risk of recurrence, socioeconomic status and diabetes were the only independent predictors of new stroke events. Additionally, we found a lower all-cause mortality in younger patients with PFO.
