Penetrating brain injury with a nail gun: technical considerations and the role of cerebral angiography. Illustrative case.

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
backgroundNail gun injuries are rare forms of penetrating brain injuries that can be associated with significant morbidity and mortality. Management strategies differ greatly in previously reported cases. OBSERVATIONS: A male in his 40s presented with an accidental, work-related nail gun injury to the left parietal lobe with no focal neurological deficits. Noncontrast CT imaging of the head and vessel imaging including CT angiography and venography were performed that demonstrated the retained nail with trace surrounding intraparenchymal hemorrhage but no obvious vascular injury. The patient underwent a preoperative diagnostic cerebral angiography that confirmed no vascular injury. The patient was then taken to a hybrid operating room/angiography suite for a burr hole craniotomy for nail removal. Selective left internal carotid artery intraoperative angiography was performed to confirm there was no contrast extravasation after nail removal. The patient was discharged home on postoperative day 1 on prophylactic antibiotics. Follow-up angiography did not demonstrate pseudoaneurysm formation. LESSONS: Nail gun injuries require a comprehensive, multidisciplinary approach to minimize the risk of complications, particularly related to vascular injury. Judicious use of preoperative and intraoperative catheter-based angiography can facilitate safe, efficient nail removal and is imperative in assessing immediate and delayed sequelae of penetrating trauma. https://thejns.org/doi/10.3171/CASE25476.
