Sub-2 mm Radial Arterial Access for Endovascular Embolization of an Idiopathic Intramammary Pseudoaneurysm: A Case Report.
Article in Cureus, 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
Radial arterial access is a relatively uncommon vascular access site. In the Indian subcontinent, the radial artery diameters are usually sub-2 mm. Here, we present a case of a spontaneous intramammary pseudoaneurysm (Im-PSA) arising from the left internal mammary artery, which was endovascularly treated via a sub-2 mm left radial access. Intermittent 50 µg nitroglycerine (NTG) was instilled every 15-20 minutes via the sheath, intraprocedurally, and a bolus of 100 µg NTG was instilled before a 1:1 sheath-catheter flush configuration. There was no intraprocedural radial artery spasm or postprocedural thrombosis. The preprocedural and intraprocedural steps have been outlined for ease of radial access in such a subset of patients. Im-PSAs are common after percutaneous breast biopsies, and spontaneous Im-PSAs are rare. We recommend that radial access via sub-2 mm radial arteries can be safely and successfully performed for subclavian or visceral arterial pathologies.
