1 · What the graph read from it

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.

2 · The registry

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

Digital tomosynthesis-guided vacuum-assisted breast biopsy is a standard minimally invasive technique for diagnosing focal breast lesions, with vascular complications such as pseudoaneurysm formation being exceedingly rare. We report the case of a 64-year-old postmenopausal woman who developed a 2.6-cm intramammary pseudoaneurysm in the right breast following digital tomosynthesis-guided vacuum-assisted breast biopsy for high-grade ductal carcinoma in situ adjacent to an invasive carcinoma with choriocarcinomatous differentiation, successfully treated with ultrasound-guided percutaneous thrombin injection, without complications. This case emphasizes the importance of early recognition of post-biopsy pseudoaneurysms to avoid potential hemorrhagic complications. Furthermore, this case demonstrates that ultrasound-guided breast thrombin injection is a safe and effective minimally invasive treatment option and highlights the importance of individualized therapeutic approaches to optimize outcomes.
