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
backgroundPatent foramen ovale (PFO) is increasingly recognized as a cause of stroke, with a prevalence of approximately 25% in the general population. Consequently, the likelihood of encountering a 'bystander PFO' in young patients who have experienced a stroke seems significant. To aid in identifying patients with a PFO-related cryptogenic stroke, an interdisciplinary Heart-Stroke Team (HST) has been established. This team evaluates patients who have suffered from stroke and were diagnosed with a PFO to assess its potential contribution. Understanding the anatomical features of PFOs associated with stroke is essential for decision-making. This study examines the PFO characteristics of all patients who underwent percutaneous PFO closure for cryptogenic stroke at two congenital heart disease institutions in the Netherlands.
methodsData on all patients who underwent PFO closure from 2016 to 2022 were collected. Anatomical characteristics were measured using transesophageal echocardiography and analyzed by two cardiologists.
resultsIn total, 223 patients underwent PFO closure. The mean age was 42.8 ± 10.7 years, with 115 (51.6%) being male. Approximately 80% of all patients had at least one risk-enhancing PFO feature (moderate to severe shunt and/or atrial septal aneurysm of > 10 mm).
conclusionAlthough all patients accepted for percutaneous PFO closure were individually assessed by a dedicated HST, 20% had a PFO without risk-enhancing features but were still accepted for closure due to other reasons. This highlights the importance of careful individual assessment of young stroke patients with a PFO. Future studies are needed to identify the characteristics that contribute to stroke in these patients.
