Small-Vessel Thrombotic Vasculopathy Secondary to Paradoxical Emboli Traversing a Patent Foramen Ovale: A Vasculitis Mimic.
Article in Case reports in rheumatology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Paradoxical thromboembolism via intracardiac defects have been described to cause limb ischaemia by occluding medium- to large-vessels. No cases have described injury to only the small vessels of the feet. We present a case of a 20-year-old male presenting with painful dusky digits of both feet who was initially thought to have a small-vessel vasculitis, but instead found on histopathological examination to have acute thrombotic vasculopathy causing cutaneous ischaemia. He was subsequently found to have a patent foramen ovale (PFO) but no thrombosis elsewhere. This case underscores the importance of transthoracic echocardiography (TTE) in patients presenting with small-vessel ischaemia, even in the absence of deep venous thromboses.
