To dig oneself into a hole or to dig the tunnel to the core? A study on the Swartz sheath support strategy for patent foramen ovale closure in migraine patients.

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
Objectives: Patent foramen ovale (PFO) closure effectively alleviates symptoms in patients with migraines; however, multipurpose angiographic catheters often encounter difficulty in passing through a small shunt PFO. Here, we present a procedural approach for the treatment of small-shunt PFO and mid-term therapeutic outcomes. Methods: Patients with migraine and concomitant PFO who visited our hospital between January 2020 and December 2022 were enrolled and grouped according to the application of the Swartz sheath support strategy (SSSS). Baseline characteristics, examination results, and surgical information were recorded. All patients were followed up for > 12 months, with the primary clinical endpoints being relief and cessation of migraine. Results: A total of 285 patients were included, of whom 82 (28.8%) underwent the SSSS. No surgery-related complications were observed in the SSSS group. The relief ( Conclusions: The SSSS is a safe and feasible technique for PFO closure in patients with migraine and difficult catheter passage, with postoperative improvement in migraine symptoms observed.
