From shadows to light: navigating the rare complication of cerebral air embolism from a case report.
Article in Frontiers in medicine, 2026. 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
We report a female patient who underwent computed tomography (CT)-guided percutaneous lung biopsy due to a right lung mass. After the procedure, she developed impaired consciousness. Non-contrast cranial CT revealed small intracranial air bubbles. Diffusion-weighted magnetic resonance imaging showed multiple acute cerebral infarctions. Whole-brain angiography did not reveal any major vessel occlusion. She was diagnosed as iatrogenic cerebral air embolism. After admission, she received intensive treatment including 100% oxygen inhalation and hyperbaric oxygen therapy. Eventually, she regained consciousness and was discharged successfully. Cerebral air embolism is a rare but severe complication of percutaneous lung biopsy with a generally poor prognosis. Clinicians should maintain a high index of suspicion for this condition in patients presenting with acute neurological deficits after lung biopsy. Hyperbaric oxygen therapy demonstrates significant neuroprotective effects and improves clinical outcomes.
